Final answer:
The compound P4S10 is named tetraphosphorus decasulfide, and calculating the amount produced from a given mass of reactants requires determining the limiting reagent and stoichiometry based on their molar masses.
Step-by-step explanation:
The compound with the formula P4S10 is named tetraphosphorus decasulfide. This compound is the result of the reaction between elemental phosphorus (P) and elemental sulfur (S) under certain conditions. In a stoichiometric reaction, reacting 10.0 g of phosphorus (P4) with 30.0 g of sulfur should yield a specific amount of tetraphosphorus decasulfide based on the molar mass of P4 and S, and the stoichiometry of the reaction.
To calculate the amount of P4S10 that can be formed, one would need to determine the limiting reagent by comparing the mole ratio from the balanced chemical equation with the moles of substances provided in the problem.
