Questions that challenge the premise(s) of an argument, the interpretation of a data set, or the suitability of a design. Doing so resulted in a much higher product mass than they had predicted since there was still unreacted sodium bicarbonate in the test tube. In this demonstration, students will observe a chemical reaction, and see how the product can be used to extinguish a fire. Products are made from the reactants, so adding more reactants will produce more of the products. Baking soda stoichiometry lab answers. There are one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms in every unit of sodium bicarbonate.
