Now consider a situation in which 29.0 g of P4 is added to 54.0 g of Cl2, and a chemical reaction occurs. To identify the limiting reactant, you will need to perform two separate calculations:

  1. Calculate the number of moles of PCl5 that can be produced from 29.0gofP4 (and excessCl2).
  2. Calculate the number of moles of PCl5 that can be produced from 54.0gofCl2 (and excessP4).

Then, compare the two values. The reactant that produces the smaller amount of product is the limiting reactant.

1) What mass of PCl5 will be produced from the given masses of both reactants? Express your answer to three significant figures and include the appropriate units. these 2 question  different from question 1

2) How much heat, in kilocalories, is produced when 3.40 g of ethanol reacts with O2gas? Express the heat to three significant figures and include the appropriate units.

3) How many grams of ethanol would need to react to produce 1450 kJ of heat? Express the mass to three significant figures and include the appropriate units.
