Is mg(c1o3)2 to mgc12+o2 balanced or unbalanced?

Unbalanced

Explanation:

For an equation to be balanced, there needs to be equal number of atoms of each elements in the reactant side and the product side.

In the chemical reaction:

Mg(ClO₃)₂ → MgCl₂ + O₂

Look at the number of atoms in the reactant side and compare them to the number of atoms in the product side

Reactant              Product

Mg = 1                   Mg = 1

Cl = 2                    Cl = 2

O = 6                     O = 2

The number of oxygen atoms on the reactant side is not equal to the number of oxygen atoms on the product side. This means that they are not equal.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

the correct answer is:

a. formation of precipitation
