Concept explainers
(a)
Interpretation:
The limiting reactant and the theoretical yield in grams of carbon dioxide need to be determined.
Concept Introduction:
The first step is to have a balanced
After that, determine the number moles present in each of the reactant by simply dividing the given mass by the molar mass of the reactant. After obtaining the number of moles of the reactant, using the balance chemical reaction, relate the number of moles of the reactants to the moles of the product
(a)
Answer to Problem 60A
The balanced reaction is:
limiting reagent is O2(g)
Theoretical yield of CO2=45.83 g
Explanation of Solution
The balanced reaction is as follows:
1 mole of C2H5OH(l) reacts with 3 moles of O2(g) to form 2 moles of CO2.
Here, limiting reagent is O2(g).
(b)
The limiting reactant and the theoretical yield in grams of nitrogen oxide need to be determined.
Interpretation:
