For the exothermic reaction n2(g)+3h2(g)→2nh3(g) what will happen if hydrogen gas was removed from the reaction mixture?

Answer is: There will be a shift toward the reactants.

Balanced chemical reaction: N₂ + 3H₂ ⇄ 2NH₃.

According to Le Chatelier's Principle the position of equilibrium moves to counteract the change.

According to Le Chatelier's principle: if the concentration is changed, that will shift the equilibrium to the side that would reduce that change in concentration.

The equilibrium shift to the left, so more hydrogen will be produced.

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

hope this : -)
