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)

lol idk man i guess u gotta ask bill nye the science guy

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
