Identify the oxidising agent (oxidant) in the following reactions
`V_(2)O_(5) + 5Ca to 2V + 5CaO`

Explanation

To identify the oxidizing agent in the reaction \( V_2O_5 + 5Ca \rightarrow 2V + 5CaO \), we can follow these steps:

### Step 1: Understand the Reaction
The reaction involves vanadium pentoxide (\( V_2O_5 \)) reacting with calcium (\( Ca \)) to produce vanadium (\( V \)) and calcium oxide (\( CaO \)).

### Step 2: Assign Oxidation States
- In \( V_2O_5 \), the oxidation state of vanadium (V) is +5.
- In elemental vanadium (\( V \)), the oxidation state is 0.
