Consider the reaction: $$ 4 \mathrm{~K}(s)+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{~K}_{2} \mathrm{O}(s) $$ The molar mass of $\mathrm{K}$ is $39.10 \mathrm{~g} / \mathrm{mol}$, and that of $\mathrm{O}_{2}$ is $32.00 \mathrm{~g} / \mathrm{mol}$. Without doing any calculations, pick the conditions under which potassium is the limiting reactant and explain your reasoning. a. $170 \mathrm{~g} \mathrm{~K}, 31 \mathrm{~g} \mathrm{O}_{2}$ b. $16 \mathrm{~g} \mathrm{~K}, 2.5 \mathrm{~g} \mathrm{O}_{2}$ c. $165 \mathrm{~kg} \mathrm{~K}, 28 \mathrm{~kg} \mathrm{O}_{2}$ d. $1.5 \mathrm{~g} \mathrm{~K}, 0.38 \mathrm{~g} \mathrm{O}_{2}$
Consider the reaction: $$4 \mathrm{K}(\mathrm{s})+\mathrm{O}_{2}(g) \longrightarrow 2 \mathrm{K}_{2} \mathrm{O}(s)$$ The molar mass of $\mathrm{K}$ is $39.10 \mathrm{g} / \mathrm{mol},$ and that of $\mathrm{O}_{2}$ is 32.00 $\mathrm{g} / \mathrm{mol} .$ Without doing any calculations, pick the conditions under which potassium is the limiting reactant and explain your reasoning. \begin{equation} \begin{array}{ll}{\text { a. } 170 \mathrm{gK}, 31 \mathrm{gO}_{2}} & {\text { b. } 16 \mathrm{gK}, 2.5 \mathrm{gO}_{2}} \\ {\text { c. } 165 \mathrm{kg} \mathrm{K}, 28 \mathrm{kgO}_{2}} & {\text { d. } 1.5 \mathrm{g} \mathrm{K}, 0.38 \mathrm{gO}_{2} \mathrm{O}_{2}}\end{array} \end{equation}
Consider the reaction: $$ 4 \mathrm{~K}(s)+\mathrm{O}_{2}(g) \rightarrow 2 \mathrm{~K}_{2} \mathrm{O}(s) $$ The molar mass of $\mathrm{K}$ is $39.09 \mathrm{~g} / \mathrm{mol}$ and that of $\mathrm{O}_{2}$ is $32.00 \mathrm{~g} / \mathrm{mol}$.
