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)
Equation (1)
0.515 g NaHCO3 x
(mass of your unknown)

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

u i forgot the answer?

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
