Answer:

Explanation:

A chemical formula is representation of a compound. Compounds are made up of two or more elements combining together.

The chemical formula of any compound is a representation which shows the elements therein and the mole relationship expressed as subscripts.

For example, HCl;

Elements in HCl - Hydrogen (H)

Chlorine (Cl)

Here 1 mole of hydrogen chloride molecule consists of 1 mole of chlorine atoms and 1 mole of hydrogen atoms.

For a phase change, H0 = 2 kJ/mol and A S0 = 0.017 kJ/(K•mol). What are

34kurt

Answer:

ΔG = -6.5kJ/mol at 500K

Explanation:

We can find ΔG of a reaction using ΔH, ΔS and absolute temperature with the equation:

ΔG = ΔH - TΔS

Computing the values in the problem:

ΔG = ?

ΔH = 2kJ/mol

T = 500K

And ΔS = 0.017kJ/(K•mol)

Replacing:

ΔG = 2kJ/mol - 500K*0.017kJ/(K•mol)

ΔG = 2kJ/mol - 8.5kJ/mol
