Identify the oxidizing agent, the reducing agent, the substance being oxidized and the substance being reduced?

Question

1.CH4(gas) + 2O2(gas) = CO2(gas) + 2H2O(liquid)

2. Zn(solid) + 2HCl(aqueous) = ZnCl2 (aqueous) + H2(gas)

Answer 1

1. Oxidizing agent: O2(gas)
Reducing agent: CH4(gas)
Substance being oxidized: CH4(gas)
Substance being reduced: O2(gas)

2. Oxidizing agent: HCl(aqueous)
Reducing agent: Zn(solid)
Substance being oxidized: Zn(solid)
Substance being reduced: HCl(aqueous)
