Balance the following reaction:

[tex]\[ \text{Ga} + \text{H}_2\text{SO}_4 \rightarrow \text{Ga}_2(\text{SO}_4)_3 + \text{H}_2 \][/tex]

List the coefficients in order, with commas and no spaces between numbers. If there is no coefficient, it is 1.

Example: For the reaction [tex]\(2 \text{H}_2 + \text{O}_2 \rightarrow 2 \text{H}_2\text{O}\)[/tex], the correct answer is 2,1,2.

Your answer: [tex]\(\square\)[/tex]



Answer :

To balance the chemical equation [tex]\( \text{Ga} + \text{H}_2\text{SO}_4 \rightarrow \text{Ga}_2\left(\text{SO}_4\right)_3 + \text{H}_2 \)[/tex], follow these steps:

1. Identify the atoms involved on both sides of the equation:
- Ga (Gallium)
- H (Hydrogen)
- S (Sulfur)
- O (Oxygen)

2. Write down the initial counts for each atom on both sides of the equation:
- Reactants:
- Ga: 1
- H: 2
- S: 1
- O: 4
- Products:
- Ga: 2
- H: 2
- S: 3
- O: 12

3. Balance Gallium (Ga):
- On the reactant side: 1 Ga
- On the product side: 2 Ga
- To balance, put a coefficient of 2 in front of Ga:
[tex]\[ 2 \text{Ga} + \text{H}_2\text{SO}_4 \rightarrow \text{Ga}_2\left(\text{SO}_4\right)_3 + \text{H}_2 \][/tex]

4. Balance Sulfur (S) and Oxygen (O):
- Sulfur (S): On reactant side: 1 S in [tex]\(\text{H}_2\text{SO}_4\)[/tex], and on product side: 3 S in [tex]\(\text{Ga}_2\left(\text{SO}_4\right)_3\)[/tex]
- To balance, put a coefficient of 3 in front of [tex]\( \text{H}_2\text{SO}_4 \)[/tex]:
[tex]\[ 2 \text{Ga} + 3 \text{H}_2\text{SO}_4 \rightarrow \text{Ga}_2\left(\text{SO}_4\right)_3 + \text{H}_2 \][/tex]

5. Balance Hydrogen (H):
- On the reactant side: [tex]\(3 \times 2 = 6\)[/tex] H atoms in [tex]\( 3 \text{H}_2\text{SO}_4 \)[/tex]
- On the product side: 2 H atoms in [tex]\( \text{H}_2 \)[/tex]
- To balance, put a coefficient of 3 in front of [tex]\( \text{H}_2 \)[/tex]:
[tex]\[ 2 \text{Ga} + 3 \text{H}_2\text{SO}_4 \rightarrow \text{Ga}_2\left(\text{SO}_4\right)_3 + 3 \text{H}_2 \][/tex]

Hence, the coefficients in order are:
[tex]\[2,3,1,3\][/tex]

So the correct answer is:
[tex]\[2,3,1,3\][/tex]
