For the following reaction at a certain temperature H₂(g) + F₂(g) ⇌ 2HF(g)

the equilibrium concentrations in a 10.00-L rigid container are [H₂] = 0.0600 M, [F₂] = 0.0200 M, and [HF] = 0.620 M. If 0.280 moles of F₂ is added to the equilibrium mixture, calculate the concentration of H₂ after equilibrium is reestablished

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
