I have four questions that I really am not sure how to do. I'll show what I have done so far....
1. How much energy would one mole of HCl require to decompose?
1 mol= ?/HCl2
2. What is the entropy change for 4Al(cr) + 3O2 ---> 2Al2O3?
205.138 + 615.414 = about 728 J/K
3. What is the free energy change for the following reaction?
HBr(g) + NH3(g) -----> NH4Br
4. If 10 grams of the sugar C12H22O11 burned in a calorimeter and produced a 5.5 degree C temperature change in 1500 grams of water, what would be the heat of combustion of 1 mole of sugar?
thank you sooo much!
