Question

YALL can you please answer this

Write a balanced chemical equation for the reaction that occurs when calcium metal undergoes a combination reaction with O2(g).

Answer 1

CaO
`_(s)`

Step-by-step explanation:

The chemical reactants are;

Calcium metal = Ca
`_(s)`

Oxygen gas = O₂
`_(g)`

Now let us write the reaction:

2Ca
`_(s)` + O₂
`_(g)` → 2CaO
`_(s)`

The product is CaO in solid form.

This reaction is a combination or synthesis reaction in which two substances combine to give a single product.
