Question

Balance the equation Mg(OH)2(aq) + 2HBr(aq) → MgBr2(aq) + 2H2O(l)

Answer 1

Mg(OH)2(aq) + 2HBr(aq) → MgBr2(aq) + 2H2O(l)

Step-by-step explanation:

This is a chemical equation that involves a reaction between magnesium hydroxide and hydrobromic acid.

In this equation, we have one molecule of magnesium hydroxide (Mg(OH)2) reacting with two molecules of hydrobromic acid (HBr) to produce one molecule of magnesium bromide (MgBr2) and two molecules of water (H2O).

To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides of the equation. Here's how we can balance this equation:

Mg(OH)2(aq) + 2HBr(aq) → MgBr2(aq) + 2H2O(l)

On the left side of the equation, we have one magnesium (Mg), two hydrogens (H), two bromines (Br), and two oxygens (O). On the right side of the equation, we have one magnesium (Mg), two hydrogens (H), two bromines (Br), and two oxygens (O).

Answer 2

Answer:Mg(OH)2(aq) + 2HBr(aq) --> MgBr2(aq) + 2H2O(l) is already balanced.

Step-by-step explanation:

This equation is already balanced. For an equation to be balanced, you want an equal number of moles of each atom on both sides of the equation.

There is

1 Magnesium

2 Oxygen

4 Hydrogen

and

2 Bromide

On our reactants side.

There is

1 Magnesium

2 Oxygen

4 Hydrogen

and

2 Bromide

On our products side.

Thus, the equation is already balanced, you don't need to do anything else. Hope this helps!
