Solution Steps

Step 1: Classify the first reaction

The reaction is: \[ \mathrm{NaOH}(aq) + \mathrm{HBrO}(aq) \rightarrow \mathrm{NaBrO}(aq) + \mathrm{H}_2\mathrm{O}(l) \] This reaction involves the exchange of ions between two compounds, indicating it is a double replacement reaction. Additionally, it involves an acid (HBrO) and a base (NaOH), making it an acid-base reaction.

Step 2: Classify the second reaction

The reaction is: \[ \mathrm{FeSO}_4(aq) + \mathrm{PbCl}_2(aq) \rightarrow \mathrm{FeCl}_2(aq) + \mathrm{PbSO}_4(s) \] This reaction involves the exchange of ions between two compounds, indicating it is a double replacement reaction. The formation of a solid product (PbSO_4) from aqueous reactants indicates it is also a precipitation reaction.

Step 3: Classify the third reaction

The reaction is: \[ 2 \mathrm{CH}_3\mathrm{CH}_2\mathrm{CO}_2\mathrm{H}(l) + 7 \mathrm{O}_2(g) \rightarrow 6 \mathrm{CO}_2(g) + 6 \mathrm{H}_2\mathrm{O}(g) \] This reaction involves a hydrocarbon (or organic compound) reacting with oxygen to produce carbon dioxide and water, indicating it is a combustion reaction.

  2. For the reaction \(\mathrm{FeSO}_4(aq) + \mathrm{PbCl}_2(aq) \rightarrow \mathrm{FeCl}_2(aq) + \mathrm{PbSO}_4(s)\):

    • Type of reaction: Double replacement, Precipitation
    • \(\boxed{\text{Double replacement, Precipitation}}\)
  3. For the reaction \(2 \mathrm{CH}_3\mathrm{CH}_2\mathrm{CO}_2\mathrm{H}(l) + 7 \mathrm{O}_2(g) \rightarrow 6 \mathrm{CO}_2(g) + 6 \mathrm{H}_2\mathrm{O}(g)\):

    • Type of reaction: Combustion
    • \(\boxed{\text{Combustion}}\)
