Identify the oxidizing agent and the reducing agent for Ca(s)+Fe2+(aq)→Ca2+(aq)+Fe(s)

Ca reducing agent

Fe2+ Oxidizing agent

Explanation:

Ca > Ca2+ +2electrons.

Calcium loses two electrons and oxidises itself and reduces others so Ca is a reducing agent.

Fe2+ +2electrons > Fe

Fe 2+ reduces itself by gaining electron and oxidizes other so Fe2+ is Oxidizing agent.

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
