Interpret the following equation for a chemical reaction using the coefficients given: H2(g) + Cl2(g) 2 HCl(g) On the particulat
jeyben [28]

Answer:

On the particulate level: 1 molecule of H₂(g) reacts with 1 molecule of Cl₂(g) to form 2 molecules of HCl(g).

On the molar level: 1 mole of H₂(g) reacts with 1 mole of Cl₂(g) to form 2 moles of HCl(g).

Explanation:

Let's consider the following equation.

H₂(g) + Cl₂(g) → 2 HCl(g)

We can use the balanced equation to interpret the changes in two levels: the particulate level and the molar level.

On the particulate level, we consider discrete molecules.

On the particulate level: 1 molecule of H₂(g) reacts with 1 molecule of Cl₂(g) to form 2 molecules of HCl(g).

On the molar level, we think in terms of moles, considering 1 mole of particles = 6.02 × 10²³ particles.

On the molar level: 1 mole of H₂(g) reacts with 1 mole of Cl₂(g) to form 2 moles of HCl(g).
