Question

When calcium metal (Ca) reacts with oxygen gas (O2), it produces the ionic compound calcium oxide (CaO). Write the balanced equation for this reaction. Then, explain if this process meets the requirements to be considered a redox reaction.

Answer 1

Step-by-step explanation:

Hey there! Down here :D

$\bf{Ca + O_2 \longrightarrow CaO}$

Now , let's balance it by Multiplying 2 on Calcium Side.

$\sf{2Ca + O_2 \longrightarrow 2CaO}$

Is the Required Equation.

Hope it helps :)

Redox Reaction: Is it?

Yes, this is because:-

$\sf{2Ca + O_2 \longrightarrow 2CaO}$

• Here, Calcium acts as Reducing Agent
• And Oxygen is oxidizing agent.
• And also, Cao gets oxidized.

It is also a Combination reaction.

$\sf{A + B \longrightarrow AB}$

• Here A is Calcium
• Here B is Oxygen.
