4.62
grams of oxygen and 2.98 grams of carbon monoxide are placed in a closed reaction vessel and the
mixture is ignited. Combustion occurs until one of the gases is totally consumed. Calculate the grams
of carbon dioxide produced. Identify the reactant that is in excess, and determine the number of
un-reacted grams that remain.
