Carbon dioxide, at high concentrations, is toxic to the human body. In the Apollo moon missions, carbon dioxide scrubbers are used to maintain the level of carbon dioxide at a safe level in the space modules. The carbon dioxide scrubbers contain canisters of lithium hydroxide. Suggest an explanation how the carbon dioxide scrubber works and give a balanced equation (without state symbols and assuming that the relevant chemicals can react directly with each other) to support your answer.

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.

it's c (engineer's do their work with mechanical stuff not on any living being)
