Homework Help: Chemistry

Posted by M on Sunday, September 16, 2012 at 6:24pm.

The fizz produced when an Alka-SeltzerŪ tablet is dissolved in water is due to the reaction between sodium bicarbonate (NaHCO3) and citric acid (H3C6H5O7): In a certain experiment 1.45g of sodium bicarbonate and 1.45g of citric acid are allowed to react.

How many grams of the excess reactant remain after the limiting reactant is completely consumed?

3NaHCO3+H3C6H5O7-->3CO2+3H2O+Na3C6H5O7

Step-by-step explanation much appreciated with as much detail as possible so I can understand. Thanks!
