Concept explainers
(a)
Interpretation:
The moles of O2 needed to react completely with 0.225 mol of C3H4 should be determined.
Concept Introduction:
A balance chemical equation provides complete information about the reactant involves in the reaction and also about the product molecules formed during the reaction. The mole concept is used to calculate moles of reactant and product which can convert to grams with the use of molar mass.
(b)
Interpretation:
The mass of water produced from the complete reaction of 64.0 g of O2 should be determined.
Concept Introduction:
A balance chemical equation provides complete information about the reactant involves in the reaction and also about the product molecules formed during the reaction. The mole concept is used to calculate moles of reactant and product which can convert to grams with the use of molar mass.
(c)
Interpretation:
The mass of CO2 produced from the complete reaction of 78.0 g of C3H4 should be determined.
Concept Introduction:
A balance chemical equation provides complete information about the reactant involves in the reaction and also about the product molecules formed during the reaction. The mole concept is used to calculate moles of reactant and product which can convert to grams with the use of molar mass.
(d)
Interpretation:
The percent yield of CO2 for the reaction should be determined.
