Reactions Properties I. \(\text{Fe} \, (s) + 2\text{HCl} \, (aq) \rightarrow \text{FeCl}_2 \, (aq) + \text{H}_2 \, (g)\) \(\text{Fe}\) is reductant II. \(\text{Zn} \, (s) + \text{CuSO}_4 \, (aq) \rightarrow \text{ZnSO}_4 \, (aq) + \text{Cu} \, (s)\) \(\text{Cu}\) is being reduced III. \(\text{Br}_2 \, (l) + 2\text{I}^- \, (aq) \rightarrow 2\text{Br}^- \, (aq) + \text{I}_2 \, (s)\) \(\text{Br}_2\) is reductant IV. \(\text{CH}_4 \, (g) + 2\text{O}_2 \, (g) \rightarrow \text{CO}_2 \, (g) + 2\text{H}_2\text{O} \, (l)\) \(\text{C}\) atom in \(\text{CH}_4\) is oxidized
Which of the above pairs are correct?
I, II and IV
To determine which pairs of reactions and properties are correct, let's analyze each option individually:
- Reaction I: \(\text{Fe} \, (s) + 2\text{HCl} \, (aq) \rightarrow \text{FeCl}_2 \, (aq) + \text{H}_2 \, (g)\)
- Reaction II: \(\text{Zn} \, (s) + \text{CuSO}_4 \, (aq) \rightarrow \text{ZnSO}_4 \, (aq) + \text{Cu} \, (s)\)
- Reaction III: \(\text{Br}_2 \, (l) + 2\text{I}^- \, (aq) \rightarrow 2\text{Br}^- \, (aq) + \text{I}_2 \, (s)\)
- Reaction IV: \(\text{CH}_4 \, (g) + 2\text{O}_2 \, (g) \rightarrow \text{CO}_2 \, (g) + 2\text{H}_2\text{O} \, (l)\)
Based on the analysis, the correct pairs are I, II, and IV.
