1. Mr. Tanner had heartburn, which is an indicator of too much acid in the stomach, that moves up into the throat. He took some Milk of Magnesia, an antacid which
helps to make the acid less acidic and burn less in the throat. The chemical
reaction combines to produce water (H,0) and magnesium (Mg). The balanced
chemical equation identifies the reactants, the products, and the masses for each
one. (S8P18)
Mg(OH)2 + 2H - 2H2O + Mg
58 g + 29 → ? + 24 g
Which mass of water (H20) is produced in this reaction?
20 g
A.
16 g
B.
C. 329
D. 36 g

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution. calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
