give the balanced thermochemical equation for the following

give the balanced thermochemical equation for the following reactions. show the correct physical state in each equation. calculate the enthalpy change for each reaction.

A.) the formation of 1 mol of HCl(gas) from its element

B.) the formation of 1 mol of sodium chloride from its elements

C.) the combustion of 1 mol glucose to water and carbon dioxide

Solution

H2(g) + Cl2(g)= 2HCl(g)                                 dG= ?92.30 kJ/mol

2Na(s) + Cl2(g)= 2NaCl(s)                            dG= ?411.12 kJ/mol

C6H12O6(s) + 6O2(g) = 6CO2(g) + H2O(l)      dG= - 2807.98 kJ/mol
