Consider the unbalanced equation for the oxidation of aluminum. _Al + _O2 Right arrow. _Al2O3 Which sequence of coefficients should be placed in the blanks to balance this equation? 2, 3, 1 1, 3, 2 4, 3, 2 3, 2, 3

4,3,2

Explanation:

if you balance a chemical equation that is the correct coefficients to be placed in the blank space

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.
