I'd love if someone would help me with this, I want to know if my answers are correct.

I. For the reaction shown, compute the theoretical yield of product (in moles) for each of the following initial amount of reactants.

2Mn(s) + 2O2(g) ---> 2MnO2(s)

1. 3 mol Mn, 3 mol O2
Answer: 3 mol MnO2(s)

2. 4 mol Mn, 7 mol O2
Answer: 4 mol MnO2(s)

3. 27.5 mol Mn, 43.8 mol O2
Answer: 27.5 mol MnO2(s)

II. Complete and Balance each of the following equations for acid-base reactions.

1. H2SO4(aq) + Ca(OH)2(aq) ---> 2H2O(l) + CaSO4(aq)

2. HClO4(aq) + KOH(aq) ---> KClO4(aq) + H2O(l)

3. H2SO4(aq) + 2NaOH(aq) ---> Na2SO4(aq) + 2H2O(l)

Thank you very much for your time.

That's all correct, good work!

2Mn(s) + 2O2(g) ---> 2MnO2(s)

Is there a need to add 2? It's already balanced

This is only comment!
Two of salts, namly CaSO₄ and KClO₄ are sparingly soluble then you can also use (s) instead of (aq).

Thanks guys, I appreciate it.
