What are the spectator ions in 2h+ + so42- + ca2+ + 2r → caso4 + 2h+ + 21?

In a spacecraft, the following reaction occurs: co2(g) + 2lioh(s) -> lico3(s) + h2o(i) (i attached picture of equation) how many liters of carbon dioxide will 4 moles of lithium hydroxide (lioh) absorb? (one mole of any gads occupies 22.4 l under certain conditions of temperature and pressure. assume those conditions for this equation.) 45l 6.0l 3.0l 34l

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.
