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).

CaO

Explanation:

 The chemical reactants are;

            Calcium metal = Ca

             Oxygen gas  = O₂  

 Now let us write the reaction:

     2Ca   +  O₂  →  2CaO

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.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
