Calculate the concentration of the hydronium ion in a 3.433 * 10^(-2) M solution of potassium perchlorate acid to the correct number of significant figures or decimal places.
Calculate the theoretical mass of hydrogen chloride formed in the reaction of sulfuric acid 2.00 mol with sodium chloride 150 g. Hydrogen chloride can be prepared by the following reaction:
The root-mean-square (rms) speed of a sample of molecules was found to be 1.8 x 10^3 m s at 25C. After heating, the rms speed was found to be 4.6 x 10^3 m s. What was the temperature of the sample after heating
The mass of the KHP is 1.496 g. Before the titration the buret reading was 0.7600 mL and afterwards it was 28.13 mL. A 146.30 mL sample of a solution of sulfuric acid, H2SO4, is neutralized by 115.36 mL of the NaOH solution from the problem above.
