Determine Δngas for each of the following reactions:(b) 2H₂(g) + O₂(g) ⇄ 2H₂O(l)
elixir [45]

2H₂(g) + O₂(g) ⇄ 2H₂O(l)

Δngas = 0 - (2 +1)

           = -3

<h3>What is Δngas?</h3>

The number of moles of gas that move from the reactant side to the product side is denoted by the symbol ∆n or delta n in this equation.

Once more, n represents the growth in the number of gaseous molecules the equilibrium equation can represent. When there are exactly the same number of gaseous molecules in the system, n = 0, Kp = Kc, and both equilibrium constants are dimensionless.

<h3>Definition of equilibrium</h3>

When a chemical reaction does not completely transform all reactants into products, equilibrium occurs. Many chemical processes eventually reach a state of balance or dynamic equilibrium where both reactants and products are present.
