Chapter 3: 3.51P (page 133)

Write balanced equations for each of the following by inserting the correct coefficients in the blanks:
$_Cu (s) + {_S}_{8} (s) 鈫� {_Cu}_{2} S (s)$
${_P}_{4} O_{10} (s) + {_H}_{2} O (l) 鈫� {_H}_{3} {PO}_{4} (l)$
${_B}_{2} O_{3} (s) +_NaOH (aq) 鈫� {_Na}_{3} {BO}_{3} (aq) + {_H}_{2} O (l)$
${_CH}_{3} {NH}_{2} (g) + {_O}_{2} (g) 鈫� {_CO}_{2} (g) + {_H}_{2} O (g) + {_N}_{2} (g)$

$16 Cu (s) + S_{8} (g) 鈫� 8 {Cu}_{2} S (s)$
$P_{4} O_{10} (s) + 6 H_{2} O (l) 鈫� 4 H_{3} {PO}_{4} (l)$
$B_{2} O_{3} (s) + 6 NaOH (aq) 鈫� 2 {Na}_{3} {BO}_{3} (aq) + 3 H_{2} O (l)$
$2 {CH}_{3} {NH}_{2} (g) + 4 O_{2} (g) 鈫� 2 {CO}_{2} (g) + 4 H_{2} O (g) + N_{2} (g)$

Step by step solution

Step1. Considering the following chemical equations:

$16 Cu (s) + S_{8} (s) 鈫� 8 {Cu}_{2} S (s)$
$P_{4} O_{10} (s) + 6 H_{2} O (l) 鈫� 4 H_{3} {PO}_{4} (l)$
$B_{2} O_{3} (s) + 6 NaOH (aq) 鈫� 2 {Na}_{3} {BO}_{3} (aq) + 3 H_{2} O (l)$
$2 {CH}_{3} {NH}_{2} (g) + 4 O_{2} (g) 鈫� 2 {CO}_{2} (g) + 4 H_{2} O (g) + N_{2} (g)$

Above is the final balanced equations.

Step2. The following points define which types of information does a balanced chemical equation provides:

1). Identification of reactants and products

Example. In the above reactions, $Cu$ , $S_{8}, P_{4} O_{10}, H_{2} O, B_{2} O_{3}, NaOH, {CH}_{3} {NH}_{2}, {andO}_{2}$ are reactants, and ${Cu}_{2} S, H_{3} {PO}_{4}, {Na}_{3} {BO}_{3}, H_{2} O, {CO}_{2}, N_{2}$ are products.

2). Physical states of reactants and products.

Example. (s) solid, (g) gas, (l) liquid, and (aq) solution.
