Lead (II) oxide from an ore can be reduced to elemental lead by heating in a furnace with carbon. Calculate the expected yield of lead if 57.0 kg of lead oxide is heated with 57.0 kg of carbon. Expected yield

A mixture of n2 (g) and h2 (g) reacts in a closed container to form ammonia, nh3 (g). the reaction ceases before either reactant has been totally consumed. at this stage 1.0 mol n2, 1.0 mol h2, and 1.0 mol nh3 are present.
