Explanation:

Mg(OH)₂ + H₂SO₄ ⟶ MgSO₄ + H₂O

Let us use alphabets a,b, c and d to represent the coefficients of the compounds in the given equation:

aMg(OH)₂ + bH₂SO₄ ⟶ cMgSO₄ + ___d__H₂O

In balancing chemical equations, we must bear in mind that they must obey the law of conservation of mass. We can use two approach in balancing a reaction.

We can inspect the individual atoms to check if they are balanced. We can also do this by using a simple mathematical method.

For the given reaction:

                        aMg(OH)₂ + bH₂SO₄ ⟶ cMgSO₄ + ___d__H₂O

For Mg:

          a = c                                (i)

For O:

        2a + 4b = 4c + d                (ii)

For H:

       2a + 2b =  2d                       (iii)

For S:

         b = c                                   (iv)

If a = 1, then c = 1, b = 1

we can then use either equation (ii) or (iii) to solve for the unknown "d":

         2a + 4b = 4c + d

Making the d the subject of the equation:

        d = 2a + 4b - 4c

        d = 2(1) + 4(1) - 4(1)

        d = 2 + 4 - 4

        d = 2

The missing coefficient is 2 and the complete equation is given as:

                       Mg(OH)₂ + H₂SO₄ ⟶ MgSO₄ + 2H₂O

The reaction is a neutralization process. In neutralization, an acid and a base react together to produce salt and water. As we can see, Mg(OH)₂ combines with H₂SO₄ to produce salt and water.
