Question

Interpret the following balanced chemical equations in terms of particles, moles, and mass. Show that the law of conservation of mass is observed. a. $\mathrm{N}_{2}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{g}) \rightarrow 2 \mathrm{NH}_{3}(\mathrm{g})$ b. $\mathrm{HCl}(\mathrm{aq})+\mathrm{KOH}(\mathrm{aq}) \rightarrow \mathrm{KCl}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\mathrm{I})$ c. $2 \mathrm{Mg}(\mathrm{s})+\mathrm{O}_{2}(\mathrm{g}) \rightarrow 2 \mathrm{MgO}(\mathrm{s})$

Step 1

$\mathrm{N}_{2}(\mathrm{g})+3 \mathrm{H}_{2}(\mathrm{g}) \rightarrow 2 \mathrm{NH}_{3}(\mathrm{g})$ In this equation, we have 1 molecule of $\mathrm{N}_{2}$ reacting with 3 molecules of $\mathrm{H}_{2}$ to produce 2 molecules of $\mathrm{NH}_{3}$. In terms of Show more…
