Chapter 8, Problem 22E

For each reaction, calculate how many moles of the product form when 0. 112 mol of the reactant in color completely reacts. Assume there is more than enough of the other reactant.

a. $2\text{Ca}\left(s\right)+{\text{O}}_2\left(g\right)\to 2\text{CaO}\left(s\right)$

b. $\text{4Fe}\left(s\right)+3{\text{O}}_2\left(g\right)\to 2{\text{Fe}}_2{\text{O}}_3\left(s\right)$

c. $\text{4K}\left(s\right)+{\text{O}}_2\left(g\right)\to 2{\text{K}}_2\text{O}\left(s\right)$

d. $\text{4Al}\left(s\right)+3{\text{O}}_2\left(g\right)\to 2{\text{Al}}_2{\text{O}}_3\left(s\right)$
