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

Answer:

CaO$_{s}$

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.
