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. N2(g) + 3H2(g) - 2NH3(g)
b. HCI(aq) + KOH(aq) - KCI(aq) + H-O0
C. 2Mg(s) + 02(g) - 2MgO(s)

Answer 1

The equations obey the law of conservation of mass in that the number of moles of each component atom is balanced on both sides.

Law of conservation of mass

It states that mass is conserved during chemical reactions.

For the first equation: $N_2(g) + 3H_2(g) --- > 2NH_3(g)$, there are 2 nitrogen and 6 hydrogen atoms on the reactant and product's side respectively. Thus, the number of atoms is conserved.

For the second equation: $HCI(aq) + KOH(aq) -- > KCI(aq) + H_2O (l)$, there are an equal number of H, Cl, K, and O atoms at the reactant and product's sides. The number of atoms is also conserved.

Lastly in the equation: $2Mg(s) + O_2(g) - 2MgO(s)$, the number of each atom is also balanced on both sides.
