Please be fast! I will mark brainliest! H2O + C16H17NaO14 = CO2 + 8H20 + C2H3NaO3 Since there are 19 Hydrogen on the Reactants side, due to Law of Conservation of Mass, there must be ___Hydrogen on the Product side.

A. 0
B. 2
C. 8
D. 19

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
