Lithium hydroxide crystals are used in manned space vehicles to remove carbon dioxide gas from the air exhaled by the astronauts. The symbolic equation for this reaction is 2LiOH + CO2 → Li2CO3 + H2O
a. The formula and charge of a lithium-ion is Li+. Deduce the formula and charge of the carbonate ion.
Explain your answer.
b. A space vehicle carries a crew of 7 astronauts. Each astronaut exhales 18 moles of carbon dioxide every day. Calculate the total number of moles of carbon dioxide that the crew will exhale during a mission into space which lasts 10 days.
Show your working.
c. Calculate the mass of lithium hydroxide crystals which must be loaded on board the space vehicle to react with all the carbon dioxide exhaled during the mission.
Show your working.
