Balanced equationbalanced

2H2 + O2 → 2H2O

Coefficients: 2, 1, 2

• Verified: atom counts balance on both sides.

Step-by-step solution

1. 1. Parse equation: 2 reactant(s), 1 product(s).

2. 2. Identify elements: H, O.

3. 3. Build matrix (2×3).

4. 4. Solve linear system → coefficients: 2, 1, 2.
