Sodium bicarbonate, NaHCO3, is used in baking (baking soda), fire extinguishers, and in the
manufacture of plastics and ceramics. It decomposes according to the equation shown below. If you
decompose 3.00 moles of sodium bicarbonate, how many moles of water will be produced?
NaHCO3 βββ> Na2CO3 + H2O + CO2
a. If the moles of water is less than 1.00 mole, eliminate the ballroom.
b. If the moles of water is between 1.00 mole and 1.25 mole, eliminate the hall.
c. If the moles of water is greater than 1.25 moles, elimination the kitchen.
