Which balanced equation represents a redox reaction? 1. mg + cl2 → mgcl2 2. cao + h2o → ca(oh)2 3. hno3 + naoh → nano3 + h2o 4. nacl + agno3 → agcl + nano3

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
