Chapter 9.4, Problem 9.24QAP

For each of the following reactions. 20.0 g of each reactant is present initially. Determine the limiting reactant, and calculate the grams of product in parentheses that would be produced.

1. $4Al\left(s\right)+3O_2\left(g\right)\to 2A{l}_2{O}_3\left(s\right)\left(A{l}_2{O}_3\right)$
2. $3N{O}_2\left(g\right)+H_{2}O\left(l\right)\to 2HN{O}_3\left(aq\right)+NO\left(g\right)\left(HN{O}_3\right)$
3. $C_2{H}_{6}O\left(l\right)+3O_2\underset{\to }{\Delta }2C{O}_2\left(g\right)+3H_{2}O\left(g\right)\left(H_{2}O\right)$
