Question

balance the chemical equation using the smallest possible whole number coefficients. if the coefficient is 1, you may leave it blank. hi (g) → h₂ (g) + i₂ (g)

Explanation:

Step1: Count atoms

On left side: 1 H and 1 I. On right side: 2 H and 2 I.

Step2: Balance H and I

Multiply HI by 2. So \(2HI(g)\to H_2(g)+I_2(g)\)

Answer:

2 (for HI), 1 (for \(H_2\)), 1 (for \(I_2\))
