If a 25.0 mL sample of sulfuric acid is titrated with 50.0 mL of 0.200 M potassium hydroxide to a phenolphthalein endpoint, what is the molarity of the acid? H2SO4(aq) + 2 KOH(aq) ? K2SO4(aq) + 2 H2O(l) Answer 0.300 M 0.200 M 0.150 M 0.400 M 0.100 M
We have learned that valence bond theory helps us to predict s and p bonding in molecules. All of the following statements about molecular bonding are true, but which statement best summarizes the most basic premise for bonding in a molecule?
each successive hydrogen is more easily substituted until the trihalo species is obtained. Explain
How much of either 5.0 M HCl or 5.0 M NaOH must you add (and which one)? Assume the pka for imidazole is 7.0.
If you wanted to make a 3 liter solution of 500 mM formic acid buffer at pH 3.9 how many grams each of sodium formate (MW=68g/mol) and formic acid (MW=46g/mol) would you add

Nitrogen reacts with hydrogen according to the following equation.
The sample is diluted with 73.505 g of water. A 12.973 g aliquot of this solution is then titrated with 0.1038 M HCl. It required 29.32 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
