Data Analysis 1. Assuming your unknown is NaHCO3, use stoichiometry to calculate the theoretical yield of
solid NaCl for the reaction represented by Equation (1).
Use your mass of unknown solid weighed out in the lab as the starting point and the mole
ratio from Equation (1). Show work.
Theoretical mass or yield of NaCl if unknown is NaHCO3
NaHCO3(8) + HCl(aq)
NaCl(aq) + H200) + CO2(g)

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
