Solid phosphorus, P4(s), reacts with chlorine gas to produce solid phosphorus pentachloride. If 187.82 g of phosphorus reacts with 521.19 g of chlorine, what mass of the excess reactant should remain unreacted?

Solid phosphorus reacts with chlorine gas to form solid phosphorus pentachloride. Explain why are there 2 Cl atoms.

the reaction of solid phosphorus (P4) with a chlorine gas produces solid phosphorus pentachloride. If 16.0 grams of phosphorus is reacted with 106.0 grams of chlorine gas in a closed container that has a volume of 2.00 L and a temperature of 53.0 degrees celsius, what is the initial pressure (before the reaction starts) and the final pressure (after the reaction is completed)
