46.1 g of cesium and 13.4 g of oxygen react to produce 28.3 g of cesium oxide - If all of the cesium reacts, how many grams of cesium oxide would be produced? And If all of the oxygen reacts, how many grams of cesium oxide would be produced?

*tilts head* sounds more like a statement

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.
