Answer the following question: in a space shuttle, the co2 that the crew exhales is removed from the air by a reaction within canisters of lithium hydroxide. on average, each astronaut exhales about 650 l of co2 daily. what mass of water will be produced
when this amount reacts with lioh? the other product of the reaction is
li2co3. when answering this question include the following:
have both the unbalanced and balanced chemical equations.
explain how to find the molar mass of the compounds.
explain how the balanced chemical equation is used to find the ratio of moles (hint: step 3 in the video).
explain how many significant figures your answer needs to have.
the numerical answer
