Many computer chips are manufactured from silicon, which occurs in nature as SiO2. When SiO2 is heated to melting, it reacts with solid carbon to form a liquid silicon and carbon monoxide gas (CO). In an industrial preperation of silicon, 155.8 kg of SiO2 is allowed to react with 78.3 kg of carbon to produce 66.1 kg of silicon. How do I determine the limiting reactant,theoretical yield and percent yield for the reaction

Im studying some chemistry, and I have an equilibrium reaction, and the same one - but halved. and need to know what happens to the constant - is it halved etc.

For instance if we have CaO+H2O->Ca(OH)2
and want to find out how much caclium hydroxide will be
produced when 10g of calcium oxide reacts with 3g of water?
What is the reason/s why we cannot do a direct gram comparison instead of converting to moles to find the limiting reactant? Please help thanks!

Im taking organic chemistry for pharmacy school, and im looking for some tips on passing it, this is my weakness.
