if you start with 5 grams of carbon on the reactant side how many grams of carbon should you start with

Answers

Based on the provided information, the number of grams of carbon should you end with is 5g.

If you start with 5 grams of carbon on the reactant side, the grams of carbon you should end with 5g based on the law of conservation of mass. The law of conservation of mass, also known as principle of mass conservation postulate that for any system closed to all transfers of matter and energy, the system mass must remain constant over time, as the mass of system cannot change, so quantity can neither be added nor be removed. Hence, the law states that mass is neither created nor destroyed in a chemical reaction. Hence, the grams of reactants that one starts with, one will end with the same amount. Chemicals recombine to give a different compound in the product, the mass is still always conserved.

You move a 12-newton box 6 meters across the floor. How much work have you done?

Answers

The amount of work that has been done would be 72 Joules.

What is work done?

The work done by a body can be defined as the amount of energy transferred from one body to another body.  In other words, work is the product of force and the distance moved by the force.

This can be expressed mathematically as:

Work = force x distance moved by the force.

In this case:

Force = 12 newton

Distance = 6 meters

Work done = 12 x 6

                   = 72 NM or 72 Joules

In other words, if I move a 12 Newton box by 6 meters across the floor, the amount of work done would be 72 Joules.

calculate the solubility of AgCN in a solution containing 1.0M H Ksp of AgCN is 2.2e-12 Ka of HCN is 6.2e-10

Answers

The solubility of AgCN in a solution containing 1.0M H Ksp of AgCN is 2.2e-12 Ka of HCN is 6.2e-10 is 5.9 x 10^-2M.

Given concentration of H+ (M) = 1.0M

Ksp of AgCN = 2.2e-12

Ka  of HCN = 6.2e-10

AgCN ⇋ Ag+ +CN− ................Ksp

CN − + H+ ⇋ HCN................... 1/Ka​

AgCN + H+ ⇋ HCN + Ag+ ...................Ksp/Ka = K0

K0 = 2.2e-12/6.2e-10 = 0.0035 = 35 x 10-4

At Equilibrium:   AgCN + H+ ⇋ HCN + Ag+

Let the moles of [Ag+] = x

So the number of moles of [HCN] = x

K0 = [Ag+] [HCN] / [H+]

35 x 10-4 = x^2/1

x = 5.9 x 10^-2M

Hence the molar solubility of AgCN in buffer solution is 5.9 x 10^-2M.

Answers

According to stoichiometry and STP conditions ,1785.90 liters of hydrogen is produced.

What is stoichiometry?

It is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.

In the given reaction as per stoichiometry, 149.84 g of As produces 6 g hydrogen , thus, 39.3 g of As will produce 39.3×6/149.84=1.573 g.

At what temperature (if any) would the decomposition of POCl3 become spontaneous?

Answers

At T=3195.53 Kelvin, decomposition of PoCl3 becomes spontaneous.

What is meant by spontaneous?

In chemistry, spontaneous processes is one that occurs without addition of external energy. Spontaneous process can occur quickly or slowly, because spontaneity is not related to the kinetics or reaction rate.

Spontaneous reaction happens in given set of conditions without interruptions whereas the nonspontaneous reaction occurs with the help of external agents like heat or energy.

Given, ∆H=572KJ and ∆S=0.179J/K

According to thermodynamical concept;

As, T=∆H/∆S,

=572/0.179

= 3195.53 Kelvin

We know, change in Gibbs free energy (∆G)=0 ; which shows that reaction is in equilibrium.

Above this temperature the reaction becomes spontaneous and moves in  forward direction.

The potential danger involved with ingesting certain compounds is associated with their solubility in the body's aqueous environment. Which of the following would be most soluble in water ?
A.CH3CH2OH
B. CH3CH2CH2OH
C. CH3OCH2CH3

Answers

The solubility of a compound in water is determined by the type of chemical bonds present in the compound and the polarity of the molecule. Thus option B is the correct answer.

Compounds that are polar and have hydrogen bonding capability are more likely to be soluble in water.

In this case, Propanol (CH3CH2CH2OH) has a polar -OH group, which makes it able to form hydrogen bonds with water molecules, and therefore it would be more soluble in water than the other two compounds.

The other two compounds, CH3CH2OH (Ethanol) and CH3OCH2CH3 (Dimethyl ether), also have polar groups, but propanol has the most polar -OH group which is why it would be the most soluble in water.

This free energy is utilized to create the high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide. Glycolysis is a series of 10 enzyme-catalyzed processes. The initial stage in the breakdown of glucose to extract energy for cellular metabolism is glycolysis. Glycolysis is divided into two phases: energy-requiring and energy-releasing.

Answers

Formal charge for nitrogen atoms I, II, and III, respectively in the azide provided is 0, +1, and -1

A formal charge, in the covalent chemical bonding, refers to the hypothetical charge assigned to an atom in a molecule, based on the assumption that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity. In other words, formal charge is defined as the difference between the number of valence electrons of an atom in a neutral free state and the number assigned to that atom in a Lewis structure. It is given as

Formal charges = Group variance – nonbonding electrons – ½ bonding electron

For the nitrogen atom I,

Formal charges =5 – 2 – ½ (6) = 0

For the nitrogen atom II,

Formal charges =5 – 0 – ½ (8) = 1

In comparison to non-polar hydrocarbon dielectrics like gasoline and diesel fuel, methanol is a polar substance like water and has a relatively high conductivity (conductivities less than 1 x 10⁴ pS/m).

Does methanol have a higher conductivity than water?

Therefore, the self dissociation into ions for methanol and ethanol will be less strong than in water. But even in pure ethanol and methanol solutions, these ions will still exist and conduct electricity, albeit at very low conductivities.

Metal reactivity decreases on moving from left to right in the modern periodic table due to the decrease in atomic size and inability to lose valence electrons.

Metals have the tendency to lose electrons and form cations. In the modern periodic table, consisting of 7 horizontal periods and 18 vertical  groups, when we move left to right across a period, the size of atoms decreases and the nuclear pull also increases due to which the elements cannot readily lose electrons and show metallic property.

How many particles foes 8.0 moles represent?

Answers

1 mole of any substance contains 6.023 × 10²³ particles. Therefore, 48.184 particles represents 8.0 moles.

What is mole ?

The term mole is defined as the amount of substance in a system which include as many elementary entities as there are atoms present in it. It is denoted by the symbol “mol”. The word mole is coming from the Latin word moles, which means “a mass”.

The mole is also defined as it contain exactly 6.023 × 10²³ elementary entities present in it. 1 mole is exactly equal to the 6.023 × 10²³ elementary entities.

1 mole =  6.023 × 10²³

8 mole = 8 × 6.023 × 10²³

= 48.184 particles

By reversing the flow of electricity, the poles of an electromagnet may be reversed. As a result, the following statement is true.

An electromagnet is a magnet that uses electricity to operate. In contrast to a permanent magnet, the strength of an electromagnet may be readily altered by varying the amount of electric current flowing through it. By reversing the flow of electricity, the poles of an electromagnet can even be reversed.

An electromagnet is created when an electric current produces a magnetic field. The resulting magnetic field surrounds the original electric current, forming circles
When an electric current is passed through a wire, the magnetic field created can be concentrated within certain areas. This effect can be further strengthened by wrapping the wire around a stable core. Certain materials, such as ironnickel and cobalt, have atoms that act like tiny magnets. 
As the current flows around the core, increasing in intensity until all of the atoms are aligned, the magnetic field becomes stronger. At some point, however, this will happen and further increases in electric current will not affect the magnetization.
