Expert Solution

Answer to Problem 25CR

$Pb(NO3)2(aq) + Na2S(aq) → PbS(s) + 2NaNO3(aq)$ .

Explanation of Solution

This is a precipitation reaction in which PbS precipitate is formed. This is also a double displacement reaction which is the two reactants have exchanged their anions. In the unbalanced equation, $Pb(NO3)2(aq) + Na2S(aq) → PbS(s) + NaNO3(aq)$ number of Na atoms in reactants side is two, but one in the products side. So we place 2 before NaNO₃. Then the whole equation gets balanced. So the balanced equation is, $Pb(NO3)2(aq) + Na2S(aq) → PbS(s) + 2NaNO3(aq)$ .

$2 Mg(s) + O2(g) → 2 MgO(s)$ .

Explanation of Solution

This is a combustion reaction in which Mg is rapidly reacting with oxygen producing a flame and MgO solid. This is also an oxidation reduction reaction where Mg has oxidized and O₂ has reduced. In the unbalanced equation, $Mg(s) + O2(g) → MgO(s)$ number of O atoms in reactants side is two, but one in the products side. So we place 2 before MgO. Then number of Mg in products side becomes two. So we place 2 before Mg. So the balanced equation is, $2 Mg(s) + O2(g) → 2 MgO(s)$ .

Answer to Problem 25CR

$H2SO4(aq) + 2 KOH(aq) → K2SO4(aq) + 2 H2O(l)$ .

Explanation of Solution

This is an acid-base reaction in which H+ from the acid reacts with OH- from the base to form water. And ionic compound K₂ SO₄ salt is also formed. This is also a double displacement reaction. In the unbalanced equation, $H2SO4(aq) + KOH(aq) → K2SO4(aq) + H2O(l)$ number of K atoms in the reactants side is one but two in the products side. So we place 2 before KOH. Then number of H atoms becomes four in the reactants side. So we place 2 before H₂ O. So the balanced equation is, $H2SO4(aq) + 2 KOH(aq) → K2SO4(aq) + 2 H2O(l)$ .

Answer to Problem 25CR

$2 C4H10(l) + 13 O2(g) → 8 CO2(g) + 10 H2O(g)$ .

Explanation of Solution

This is a combustion reaction in which C₄ H₁ ₀ reacts with oxygen. This is also an oxidation reduction reaction where C₄ H₁ ₀ is oxidized and O₂ is reduced. In the unbalanced equation, $C4H10(l) + O2(g) → CO2(g) + H2O(g)$ number of C atoms in the reactants side is four, but one in the products side. So we place 4 before CO₂. Number of H atoms in the reactants side is 10, but only two in the products side. So we place 5 before H₂ O. Then number of O atoms in the products side becomes thirteen. So we place 13/2 before O₂. But we cannot keep a half integer in a balanced chemical equation. So we multiply the whole equation by two. So the balanced equation is, $2 C4H10(l) + 13 O2(g) → 8 CO2(g) + 10 H2O(g)$ .

Answer to Problem 25CR

$2 Na3PO3(aq) + 3 CaCl2(aq) → Ca3(PO4)2(s) + 6 NaCl(aq)$ .

Explanation of Solution

This is a single precipitation reaction in which Ca₃ (PO₄ )₂ precipitate is formed. This is also a double displacement reaction. In the unbalanced equation, $Na3PO3(aq) + CaCl2(aq) → Ca3(PO4)2(s) + NaCl(aq)$ number of Ca atoms in the products side is three but one in the reactants side. So we place 3 before CaCl₂. Then number of Cl atoms in the reactants side becomes six. So we place 6 before NaCl. Then number of Na atoms in the products side becomes six. So we place 2 before Na₃ PO₃. So the balanced equation is, $2 Na3PO3(aq) + 3 CaCl2(aq) → Ca3(PO4)2(s) + 6 NaCl(aq)$ .

Answer to Problem 25CR

$2 C4H10(l) + 13 O2(g) → 8 CO2(g) + 10 H2O(g)$ .

Explanation of Solution

This is a combustion reaction in which C₄ H₁ ₀ reacts with oxygen. This is also an oxidation reduction reaction where C₄ H₁ ₀ is oxidized and O₂ is reduced. In the unbalanced equation, $C4H10(l) + O2(g) → CO2(g) + H2O(g)$ number of C atoms in the reactants side is four, but one in the products side. So we place 4 before CO₂. Number of H atoms in the reactants side is 10, but only two in the products side. So we place 5 before H₂ O. Then number of O atoms in the products side becomes thirteen. So we place 13/2 before O₂. But we cannot keep a half integer in a balanced chemical equation. So we multiply the whole equation by two. So the balanced equation is, $2 C4H10(l) + 13 O2(g) → 8 CO2(g) + 10 H2O(g)$ .
