Question 11 (1 point) How many moles of O2 are required to produce 9.45 moles of Al2O3 during the following reaction:
4 Al + 302
2A1203
O a
Ob
14.3 mol 02
3.15 mol 02
6.30 mol O2
0.139 mol O2

it is a solid

explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
