Answer 2

To balance the given chemical 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 the balanced equation for the reaction between magnesium (Mg) and sulfuric acid (H2SO4) to form magnesium sulfate (MgSO4) and hydrogen sulfide (H2S):

Mg + H2SO4 → MgSO4 + H2S

Now, let's balance the equation step by step:

1. Start with the hydrogen (H) atoms: On the left side, there are 2 hydrogen atoms in H2SO4. On the right side, there are 2 hydrogen atoms in H2S.

Since the number of hydrogen atoms is already balanced, let's move on to the next element.

2. Next, balance the sulfur (S) atoms: On the left side, there is 1 sulfur atom in H2SO4. On the right side, there is 1 sulfur atom in MgSO4.

Again, the number of sulfur atoms is already balanced.

3. Finally, balance the magnesium (Mg) atoms: On the left side, there is 1 magnesium atom (Mg). On the right side, there is 1 magnesium atom (Mg).

Now, all the elements are balanced, and the final balanced equation is:

Mg + H2SO4 → MgSO4 + H2S

The equation is now balanced, and the reaction shows that magnesium reacts with sulfuric acid to produce magnesium sulfate and hydrogen sulfide.
