Given the equation representing a reaction at equilibrium:
n2(g) + 3h2(g) < ==> 2nh3(g)
what occurs when the concentration of h2(g) is increased?
(1) the equilibrium shifts to the left, and the concentration of n2(g) decreases.
(2) the equilibrium shifts to the left, and the concentration of n2(g) increases.
(3) the equilibrium shifts to the right, and the concentration of n2(g) decreases.
(4) the equilibrium shifts to the right, and the concentration of n2(g) increases.

the answer is a. co2, this would be colder than the : )

explanation:

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
