a gas sample with a mass of 2.50 g is collected at 20.0oc and 732.5 mmhg. the volume is 1.28 l. what is the molar mass of the gas?

First, we'll look at the ideal gas equation,

PV = nRT

The temperature and pressure are said to be constant; Additionally, R is a constant already. Along these lines, we get:

V = constant * n

The direct proportional equation is as follows: As a result, we get:

V/n = constant

V₁/n₁ = V₂/n₂

Replace V₂ with the qualities and address.

V₂ = (4 * 1.48) / 0.864

V₂ = 6.85

In the end, 6.85 Liters of gas must be present, so we must add:

6.85 - 4 = 2.85 liters

(S)-2-aminobutane could be used as a resolving agent for a racemic carboxylic acid.

To be used as a resolving agent, an amine must be able to form a diastereomeric salt with the racemic carboxylic acid. This salt can then be separated into its enantiomeric forms using conventional separation techniques. The key is to find an amine that will selectively react with one enantiomer of the carboxylic acid and not the other.

Out of the amines shown, only (S)-2-aminobutane has a chiral center and is therefore capable of forming diastereomeric salts with a racemic carboxylic acid. The other amines are achiral and would not be able to differentiate between the enantiomers of the carboxylic acid.

When an amine is used as a resolving agent for a racemic carboxylic acid, it reacts with the acid to form a diastereomeric salt. This salt can be separated into its enantiomeric forms using conventional separation techniques such as recrystallization or chromatography.

3020 grams of iron are produced when 27.0 moles of hematite react with 86.0 moles of carbon monoxide.

Balanced chemical equation for the reaction between hematite and carbon monoxide will be; Fe₂O₃(s) + 3CO(g) -> 2Fe(s) + 3CO₂(g)

From the balanced equation, we can see that 1 mole of Fe₂O₃ reacts with 3 moles of CO to produce 2 moles of Fe. So, to determine the amount of iron produced, we first need to determine which reactant is limiting.

We can calculate the moles of Fe₂O₃ and CO;

Moles of Fe₂O₃ = 27.0 moles

Moles of CO = 86.0 moles

To determine the limiting reactant, we need to compare the mole ratio of Fe₂O₃ to CO required by the balanced equation (1:3) to the actual mole ratio of Fe₂O₃ to CO provided.

Mole ratio of Fe₂O₃ to CO = 27.0/1 : 86.0/3 = 81 : 86 ≈ 0.94 : 1

Since the actual mole ratio of Fe₂O₃ to CO is less than the mole ratio required by the balanced equation, Fe₂O₃ is the limiting reactant.

The amount of Fe produced can be calculated using the mole ratio of Fe₂O₃ to Fe in the balanced equation.

Moles of Fe = 2/1 × moles of Fe₂O₃ = 2/1 × 27.0 moles = 54.0 moles

Finally, we can convert moles of Fe to grams of Fe using the molar mass of Fe

Grams of Fe = moles of Fe × molar mass of Fe = 54.0 moles × 55.85 g/mol = 3020 g

23.22 mL of the 23.4% irrigation solution would be required to compound the given prescription.

To prepare a 10% NaCl solution using a 0.9% solution and a 23.4% solution in stock, we can use the formula:

C1V1 + C2V2 = C3V3

where C1 is the concentration of the first solution (0.9%), V1 is the volume of the first solution (unknown), C2 is the concentration of the second solution (23.4%), and so on.

Substituting these values into the formula, we get:

(0.9%)(V1) + (23.4%)(V2) = (10%)(1000 mL)

Simplifying this equation, we get:

0.009V1 + 0.234V2 = 100 mL

We have two unknowns and one equation, so we need another equation to solve for both V1 and V2.

Let’s use a mass balance equation:

mass of NaCl in first solution + mass of NaCl in second solution = mass of NaCl in final solution

The mass of NaCl in each solution is equal to its concentration multiplied by its volume and density.

For the first solution:

mass = (0.9 g/mL)(V1 mL)(0.01 g NaCl/g)

For the second solution:

mass = (23.4 g/mL)(V2 mL)(0.01 g NaCl/g)

For the final solution:

mass = (10 g/mL)(1000 mL)(0.01 g NaCl/g)

Substituting these values into our mass balance equation, we get:

(0.9 g/mL)(V1 mL)(0.01) + (23.4 g/mL)(V2 mL)(0.01) = (10 g/mL)(1000 mL)(0.01)

Simplifying this equation, we get:

0.009V1 + 0.234V2 = 100

Now that we have two equations with two non-specific values, we can answer them both at once.

Multiplying our first equation by -26/3, we get:

-7.8V1 - 6.12V2 = -260

Adding this equation to our second equation, we get:

-6.8V2 = -160

Solving for V2, we get:

V2 = 23.22 mL

Therefore, we need 23.22 mL of the 23.4% solution to compound this prescription.

The recommended pediatric iv dosage of furosemide is 1 mg/kg not to exceed 6 mg/kg. the child weighs 55 lb. available: furosemide 20 mg/2 ml. The child will receive approximately 2.5 mL of furosemide.

To determine the appropriate dosage of furosemide for the child, first convert their weight from pounds to kilograms.

1 lb = 0.453592 kg

55 lb × 0.453592 kg/lb ≈ 24.95 kg

Now, calculate the dosage using the recommended pediatric IV dosage (1 mg/kg):

24.95 kg × 1 mg/kg ≈ 24.95 mg

Since the dosage should not exceed 6 mg/kg:

24.95 kg × 6 mg/kg = 149.7 mg (maximum dosage)

Since the child's calculated dosage (24.95 mg) is less than the maximum dosage, it can be administered.

Next, determine the volume of furosemide to be given. The available concentration is 20 mg/2 mL. Use the proportion:

20 mg/2 mL = 24.95 mg/x mL

The change in mass of the anode and cathode in an electrochemical cell can be used to determine the amount of reactants that have been converted into products during the electrochemical reaction. Therefore, the concentration of the electrolyte solution may change during the course of the electrochemical reaction.

The amount of reactants consumed at the anode will be equal to the amount of products produced at the cathode. Therefore, the change in mass of the anode should be equal in magnitude but opposite in sign to the change in mass of the cathode.

For example, in a galvanic cell where zinc is oxidized at the anode and copper is reduced at the cathode, the mass of the anode will decrease as zinc atoms are converted to Zn²⁺ ions and electrons, while the mass of the cathode will increase as copper ions are reduced to copper atoms and gain electrons.

It would take 1,127.7 kJ of thermal energy to change 500g of water from liquid phase to vapor phase at a constant temperature and pressure, assuming the theoretical heat of vaporization of water.

To calculate the amount of thermal energy required to change 500g of water from liquid phase to vapor phase, we need to use the heat of vaporization (also called enthalpy of vaporization) of water, which is the amount of energy required to convert one mole of liquid water to water vapor at a constant temperature and pressure.

The heat of vaporization of water is given as 40.65 kJ/mol. To calculate the energy required to vaporize 500g of water, we need to first calculate the number of moles of water present in 500g of water:

Number of moles of water = mass of water / molar mass of water

Number of moles of water = 500g / 18.02 g/mol

Number of moles of water = 27.74 mol

Now, we can use the following formula to calculate the amount of thermal energy required:

The volume of oxygen consumed when 458 g of CH4 is combusted at STP is 1278.14 L.

What is STP?

STP stands for Standard Temperature and Pressure, which is a standard set of conditions used in chemistry and physics experiments. The standard temperature is 0 degrees Celsius or 273.15 Kelvin, while the standard pressure is 1 atmosphere or 101.3 kilopascals (kPa). At STP, one mole of any ideal gas occupies a volume of 22.4 liters (L). These standard conditions allow scientists to compare the properties of different gases under the same conditions, making it easier to make accurate measurements and predictions.

To find the volume of oxygen consumed during the combustion of methane, we need to use the balanced chemical equation and the ideal gas law.

First, let's find the number of moles of methane used:

Molar mass of CH4 = 12.01 + 4(1.01) = 16.05 g/mol

Number of moles of CH4 = 458 g / 16.05 g/mol = 28.53 mol

According to the balanced chemical equation, one mole of CH4 reacts with two moles of O2, so we need:

28.53 mol CH4 × 2 mol O2/1 mol CH4 = 57.06 mol O2

At STP (standard temperature and pressure), one mole of any ideal gas occupies 22.4 L of volume. Therefore, the volume of oxygen consumed is:

Saltation is the skipping or bouncing motion of particles transported by running water. Saltation is a type of bedload transport in which small and medium-sized particles are lifted and moved downstream by the flow of water.

The particles that are involved in saltation are too large to be carried in suspension by the water, but too small to roll or slide along the streambed.

The term saltation comes from the Latin word "saltare," which means "to leap or dance." It is used to describe the movement of sediment particles that bounce and leap along the streambed. Saltation occurs when the velocity of the water is strong enough to lift particles from the streambed, but not strong enough to carry them in suspension.

In saltation, particles that are lifted from the streambed by the flow of water fall back to the bed after they lose momentum. This falling back to the bed causes the particles to bounce and leap along the bed in a zig-zag motion. Saltation can move sediment over a short distance, but it is an important process in stream erosion and sediment transport.

Answer: The second reaction took place at a higher temperature

Explanation:

Rate is affected by temperature, as higher temperatures cause the reacting molecules to have more energy.

Collision theory states that in order for a reaction to occur, each reacting molecule must collide with one another in the correct orientation and with enough energy, called the activation energy.

A higher energy caused by a higher temperature will cause the molecules to collide much more frequently, leading to a higher chance of a successful collision, and with more energy to satisfy the activation energy.

Therefore, the second reaction must have taken place at a higher temperature, since the molecules had more energy than the first reaction leading to a higher rate of reaction, and a higher rate constant.

The reaction in question is the water gas shift reaction:

CO2(g) + H2(g) ⇌ CO(g) + H2O(g)

At 1000 K, this reaction is endothermic, meaning that it requires heat as a reactant and will shift towards the product side at higher temperatures. However, we need to calculate the reaction quotient (Qc) for this system to determine whether the reaction will proceed towards products or reactants.

The reaction quotient Qc is defined as the product of the concentrations of the products, each raised to the power of their stoichiometric coefficients, divided by the product of the concentrations of the reactants, each raised to the power of their stoichiometric coefficients.

Qc = [CO][H2O] / [CO2][H2]

where the square brackets denote the concentration of each species.

We are given the partial pressures of each gas, but we need to convert these to concentrations using the ideal gas law:

PV = nRT

where P is the partial pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

For each gas, we can solve for the number of moles (n) and then divide by the total volume to obtain the concentration:

[CO2] = (0.0750 atm)(V) / (RT)

[H2] = (0.095 atm)(V) / (RT)

[CO] = (0.0340 atm)(V) / (RT)

[H2O] = (0.0650 atm)(V) / (RT)

where V is the total volume of the mixture.

Substituting these expressions into the equation for Qc, we obtain:

Qc = [(0.0340 atm)(0.0650 atm)] / [(0.0750 atm)(0.095 atm)]

Qc = 0.0232

If Qc < Kc, the reaction will shift towards the product side to reach equilibrium. If Qc > Kc, the reaction will shift towards the reactant side. If Qc = Kc, the reaction is at equilibrium and there is no net change.

The equilibrium constant (Kc) for the water gas shift reaction at 1000 K is not provided, so we cannot directly compare Qc and Kc. However, the small value of Qc (0.0232) suggests that the reaction is not at equilibrium and may shift towards the product side to reach equilibrium.

Therefore, based on the calculated value of Qc, the reaction may proceed towards products at 1000 K in the given mixture of gases.

Answer:

Explanation:

Yes, that is correct.

When aluminum sulfate solution (Al2(SO4)3) and calcium hydroxide solution (Ca(OH)2) are mixed, a double displacement reaction occurs, resulting in the formation of solid aluminum hydroxide (Al(OH)3) and solid calcium sulfate (CaSO4). The balanced chemical equation for this reaction is:

Al2(SO4)3 + 3Ca(OH)2 → 2Al(OH)3 + 3CaSO4

The aluminum hydroxide precipitates out of the solution as a gelatinous solid, while the calcium sulfate forms a white solid. This reaction is commonly used in water treatment plants to remove impurities from drinking water, as the aluminum hydroxide acts as a coagulant that binds to particles and organic matter in the water, allowing them to be removed more easily.

The ammonia gas's final temperature is 417.3 K. It moved from having a volume of 250 mL, a pressure of 3.84 atm, and a temperature of 35 oC to having a pressure of 5.84 atm and a volume of 215 mL.

To solve this problem, we can use the combined gas law, which states:

(P1 * V1) / (T1) = (P2 * V2) / (T2)

Where:

P1 = 3.84 atm

V1 = 250 mL

T1 = 35ºC + 273.15 = 308.15 K (temperature must be in Kelvin)

P2 = 5.84 atm

V2 = 215 mL

T2 = ?

We can rearrange this equation to solve for T2:

T2 = (P2 * V2 * T1) / (P1 * V1)

T2 = (5.84 atm * 215 mL * 308.15 K) / (3.84 atm * 250 mL)

T2 = 417.3 K

Therefore, the final temperature of the ammonia gas is 417.3 K.

The client will receive 550 ml of fluid volume over a period of 10 hours if D5W is infusing at 55 gtt/min with a drop factor of 60 gtt/ml.

To calculate the fluid volume that the client will receive in 10 hours, we need to use the following formula:

Volume (in ml) = Flow rate (in gtt/min) x Time (in min) / Drop factor (in gtt/ml)

Given that the D5W solution is infusing at a rate of 55 gtt/min and the drop factor is 60 gtt/ml, we can plug in these values to the formula:

Volume (in ml) = 55 gtt/min x 600 min / 60 gtt/ml

Simplifying the equation, we get:

Volume (in ml) = 550 ml
