The fizz produced when an alka-seltzer® tablet is dissolved in water is due to the reaction between sodium bicarbonate (nahco3) and citric acid (h3c6h5o7): 3nahco3(aq)+h3c6h5o7(aq)→3co2(g)+3h 2o(l)+na3c6h5o7(aq) in a certain experiment 1.50 g of sodium bicarbonate and 1.50 g of citric acid are allowed to react.

Look at the reaction below: ca(hco3)2 --> caco3 + co2 + h2o first, balance the reaction. once balanced, use dimensional analysis or another method to find out how many moles of carbon dioxide will be produced if we start with 16.5 moles of calcium bicarbonate (calcium hydrogen carbonate). = mol of co2 number needs to be reported to three significant figures.
