Question

Calculate ∆H°298 for each of the following reactions using suitable chemical data book.? 1. 3Zn(s) + Al2O3 ➡️ 2Al(s) + 3ZnO(s) 2. MgCO3(s) ➡️ MgO(s) + CO2

Answer 1

You have included NO data....

Explanation:

Some help is offered on this site, but you are taking the pi$$ if you expect someone to find and quote data that are listed in your own text.....Find `DeltaH_f^@` for each of the products and reactants...and then do the summation...

`DeltaH_"reaction"^@=DeltaH_f^@"(products)"-DeltaH_f^@"(reactants)"`
