A quality control chemist at Dow Chemical tried to determine purity of NaOH using titration.He measured out 0.500 g NaOH sample, and dissolved it in 20 mL water. 31.2 mL of a 0.386 mol/L HCl solution was used to reach the end point. Assume the impurity did not react with HCl, what is the %purity of this NaOH sample?

Determine how many grams of Hydrogen are required to form 14.01grams of Ammonia and calculate how many grams of ammonia could be formed
N and H undergo a combination reaction under appropriate conditions, to yield ammonia: N2 (g) +3H2 (g) →2NH3 (g), determine how much sample of N2 in grams requires 3.0 g of H2 for complete reaction.
Determine the calorimeter constant or eat capacity, for this calorimeter if the specific heat for water= 4.184 J/goC.
Note that in some cases, the "product" may be the result of a proton transfer reaction. Do not assume that an aqueous workup (H3O+) is performed unless it is specified
