Question

For the reaction, calculate how many moles of the product form when 0.016mol of O2 completely reacts.
Assume that there is more than enough of the other reactant.
2Ca(s)+O2(g)→2CaO(s)

Answer 1

if you have .016 moles of 02 then .032 mols of product will form

Answer 2

because the equation tells you for every mol of 02 you will get 2 moles of product . so you just multiply the moles by two
