Answer: The given unbalanced chemical equation is:
SiH₁₀ + O₂ → SiO₂ + H₂O
To balance this equation, you need to make sure that the same number of each type of atom is on both sides of the equation.
Explanation:
1. Start by balancing the silicon (Si) atoms. There's 1 Si on the left side and 1 Si on the right side. So, silicon is already balanced.
2. Balance the hydrogen (H) atoms. There are 10 H on the left side and 4 H on the right side (2 in H₂O). To balance the hydrogen, you need to have 2 molecules of H₂O on the right side to match the 10 H atoms on the left side.
3. Balance the oxygen (O) atoms. There are 2 O in SiH₄ and 4 O in 2O₂ on the left side. On the right side, there are 2 O in SiO₂ and 4 O in 2H₂O. In total, there are 2 + 4 = 6 O atoms on both sides, so the oxygen is balanced.
