Identifying oxidising and reducing agents.

Extracted text: Decide whether each chemical reaction in the table below is an oxidation-reduction ("redox") reaction. If the reaction is a redox reaction, write down the formula of the reducing agent and the formula of the oxidizing agent. redox reaction? O yes O no 2Ca (s) + 0,(g) → 2CaO(s) reducing agent: oxidizing agent: redox reaction? yes no c() + 0,(s) → co,6) reducing agent: oxidizing agent: redox reaction? O yes no Na, Co, () + H,PO,(aq) → Na,H PO,(aq) + Co,g) + H,0() reducing agent: oxidizing agent: 1
