1. Given the following reaction: 8CaO + Sg - 8CaS + 402
How many grams of molecular sulfur are needed to produce 27.5 L of oxygen at STP?

It will appear as o2(g) as a reactant 

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)

Answer( precipitate );

Don’t know. don’t care.look it up on google
