Write the balanced molecular chemical equation for the reaction in aqueous solution for cesium carbonate and magnesium
nitrate. If no reaction occurs, write NR.

Cs2CO3 + Mg(NO3)2 -> 2CsNO3 + MgCO3

Explanation:

This is a typical double displacement equation, and balancing this equation by adding the 2 in front of the cesium would solve this problem.

The answer in words would be :

Cesium Carbonate + Magnesium Nitrate = Cesium Nitrate + Magnesite.

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.
