The chemical equation below shows the reaction between carbon dioxide (co2) and lithium hydroxide (lioh). co2 + 2lioh mc011-1.jpg li2co3 + h2o the molar mass co2 is 44.01 g/mol. how many moles of lioh are needed to react completely with 25.5 g of co2?

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.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
