Radioactive dating measures the rate of decay of radioactive materials in rocks.

What is radioactive dating?

Radiometric dating, radioactive dating, or radioisotope dating is a technique used to date things such as rocks or carbon that included trace radioactive contaminants when they were produced. Radioactive dating is a technique for dating rocks and minerals that makes use of radioactive isotopes. This approach is appropriate for igneous and metamorphic rocks that cannot be dated using the sedimentary stratigraphic correlation method. There are around 300 naturally occuring isotopes known. The underlying idea behind radiometric dating is that you can compute the age of a sample by comparing the presence of a radioactive isotope within it to its known abundance on Earth and its known half-life (rate of decay).

15.0 L of an ideal gas at 298 K and 3.36 bar are heated to 350 K with a new pressure of 4.90 atm. What is the new volume in litres

Answers

The new volume in litres is 13.29 L.

Given,

Temperature 1 (T₁) = 298 K

Volume 1 (V₁) = 15 L

Temperature 2 (T₂) = 383 K

Pressure 1 (P₁) = 3.36 atm

Pressure 2 (P₂) = 4. atm

What is the relative rate of diffusion of CH4 and NO2?

Answers

The ratio of effusion rates of Sulphur dioxide and methane is 0.5

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

Rate of Diffusion ∝ 1 ÷ √molar mass of the gas

We are given:

Molar mass of Sulphur dioxide = 64.066 g/mol

Molar mass of methane = 16.04 g/mol

By taking their ratio, we get:

Rate of SO₂ ÷ Rate of CH₄ = √MCH₄ ÷ √MSO₂

Rate of SO₂ ÷ Rate of CH₄ = √16.04 ÷ √64.066

Rate of SO₂ ÷ Rate of CH₄ = 0.5

Hence, the ratio of rate of effusion of Sulphur dioxide and methane will be 0.5

Given that 1 kWh = 3. 6 MJ and that 1 Btu = 1055 J, show that 1 kWh = 3412 Btu.

Answers

Given that 1 kWh = 3. 6 MJ and that 1 Btu = 1055 J, It is shown that 1 kWh = 3412 Btu.

1 kilowatt (kWh) = 3.6 mega Joules (MJ)

1 British thermal unit (Btu) = 1055 Joules (J)

As we know that:

1 MJ = 1000000 J

Since

1 kWh = 3.6 x 1000000 J

Calculate for 1 J

1 J = 1 ÷ 1055 Btu

1 kWh = 3.6 x 1000000 x (1 ÷ 1055) Btu

1 kWh  = 3412.32 Btu

A 16. 81 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 21. 33 grams of CO₂ and 5. 822 grams of H₂O are produced. In a separate experiment, the molar mass is found to be 104. 1 g/mol.  The empirical formula is CH₃   and molecular formula is C₇H₇O₂₁

The empirical formula can be calculate as follows:

The reaction can be write

CxHyOz  → CO₂ + H₂O

As a result, we may state that there are two O-atoms for every one C-atom (12g) in CO2 (32g).

This indicates that the ratio is 12g C/32g O.

The molar mass of CO₂ is 44 g/mole.

(12/44) x 33 = 9 g

There are 9 grams of carbon in every 33 grams of CO₂

The same can be done for water:

In H₂O, each element is represented by two H atoms and one O atom. 2 g H and 16 g O.

[2 g H / 18 g H2O] are present in 5. 822 g of water

(2/18)x 5.822= 0.6468 g

The initial sample had 14.16 g of sample, 9 g of C, and 0.6468 g of H, which resulted in 34.3532g of oxygen.

Determine the amount of moles.

C: 9.0 g / 12.0 g/mol = 0.75 mol

H: 0.6468 g / 1.0 g/mol = 0.6468 mol

O: 34.3532g / 16.0 g/mol =  2.14 mol

Then we divide by the smallest number

C: 0.75 mol / 0.6468 mol = 1

H: 0.6468 mol / 0.6468 mol= 1

O:  2.14 mol/ 0.6468 mol =  3

so the empirical formula will be CH₃

Determine the molecular formula

mass molecular formula / mass of empirical formula = n

Coca-Cola is making a version of Coke that uses sucrose (C12H22O11) instead of high fructose corn syrup. If there are 39.24 grams of sucrose in a 12.0 fluid oz. can of this Coke, what is the molarity of sucrose in the Coke.

To find the molarity of sucrose in the Coke, we first need to find the number of moles of sucrose present in the can. We can use the mass of sucrose (39.24 g) and the molar mass of sucrose (342.3 g/mol) to find the number of moles of sucrose:

= (39.24 g) / (342.3 g/mol)

= 0.114 mol

Next, we need to find the volume of the can in liters. We can convert the volume in fluid oz. to liters using the conversion factor 1 fluid oz.

= 0.0295735 L:

= (12.0 fluid oz.) x (0.0295735 L/fluid oz.)

= 0.354882 L

Finally, we can use the formula for molarity (moles of solute / liters of solution) to find the molarity of sucrose in the Coke:

ΔS∘ for Ti(s)+2Cl2(g)→TiCl4(g) is 659.6J/mol.. It is important to note that, as a general rule, a positive ΔS° indicates an increase in disorder and a negative ΔS° indicates a decrease in disorder.

The change in entropy (ΔS) for a chemical reaction can be calculated using the standard entropies (S°) of the reactants and products.

ΔS° = S°(products) - S°(reactants). For the reaction Ti(s) + 2Cl2(g) → TiCl4(g)S° of Ti(s) = 29.1 J/mol·K, S° of Cl2(g) = 223.1 J/mol·K, S° of TiCl4(g) = 167.4 J/mol·K. Therefore, ΔS° = (S°(TiCl4) + 2S°(Cl2)) - S°(Ti)ΔS° = (167.4 + 2*223.1) - 29.1 = 659.6 J/mol·K. So the ΔS∘ for Ti(s) + 2Cl2(g) → TiCl4(g) is 659.6 J/mol·K with four significant figures. It is important to note that, as a general rule, a positive ΔS° indicates an increase in disorder and a negative ΔS° indicates a decrease in disorder. So in this case, the process of going from solid titanium and gaseous chlorine to gaseous titanium tetrachloride increases disorder, which is consistent with a positive ΔS°.

Answers

Answer:

Strong acids are defined by their pKa. The acid must be stronger in aqueous solution than a hydronium ion, so its pKa must be lower than that of a hydronium ion. Therefore, strong acids have a pKa of <-174. Strong acids can be organic or inorganic.

Explanation:

Bond Strength

Strong acids have mostly ions in solution, therefore the bonds holding H and A together must be weak. Strong acids easily break apart into ions. Weak acids exist mostly as molecules with only a few ions in solution, therefore the bonds holding H and A together must be strong.
