Given the values of ΔGfo given below in kJ/mol, calculate the value of ΔGo in kJ for the combustion of 1 mole of butane to form
xz_007 [3.2K]

Answer:

Δ_rG=-2753kJ

Explanation:

Hello,

Butane's combustion is:

C_4H_{10}+\frac{13}{2} O_2-->4CO_2+5H_2O

Now the change in the Gibbs free energy for this reaction is computed via (don't forget that oxygen's Gibbs free energy of formation is 0 since it is an element):

Δ_rG=4Δ_fG_{CO_2}+5Δ_fG_{H_2O}-Δ_fG_{C_4H_{10}}

Δ_rG=4(-395kJ/mol)+5(-238kJ/mol)-(-17kJ/mol)

Δ_rG=-2753kJ/mol

Now, since the calculation is done for 1 mol of butane, the change in the Gibbs free energy for this fuel is:

Δ_rG=-2753kJ

Best regards.

The silver in a piece of jewelry has a volume of 0.25cm^3. If the density of
sdas [7]

Answer:

The answer is

<h2>2.63 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

volume of silver = 0.25 cm³

density = 10.5 g/cm³

The mass is

mass = 10.5 × 0.25 = 2.625

We have the final answer as

<h3>2.63 g</h3>

Hope this helps you
