Which of these reactions are redox reactions? check all that apply. cd + hcl → cdcl2  + h2cucl2  + na2s → 2nacl + cuscaco3  → cao + co2          2zns + 3o2  → 2zno + 2so2          ch4  + 2o2  → co2  + 2h2o

Equal volumes of h2 and o2 are placed in a balloon and then ignited. assuming that the reaction goes to completion, which gas will remain in excess? 2h2 + o2 → 2h2o a. both are in equal proportion b. oxygen c. water d. hydrogen
