In the gravimetric determination of Zn^2+, 2.2024 g sample was dissolved and made up to volume in a 100.0 mL flask. A 10.0 mL aliquot were precipitated by adding a soluble pyrophosphate salt and heating the precipitate to a solid Zn2P2O7 (304.728 g/mol). The final, dried product weighed 0.1314 g. What is the percent weight of Zn (65.39 g/mol) in the original sample

The reaction of 0.25 g magnesium with 100 mL of 1 M hydrochloric acid (density d = 1.02 g/ml) raises the temperature of the solution from 20 °C to 35 °C . The specific heat for HCl is 3.93 J/(g.C).
If 0.214 mol of argon gas occupies a volume of 652 mL at a particular temperature and pressure, what volume would 0.375 mol of argon occupy under the same conditions?
If we attemp to add a second nitogroup to methyl m-nitrobenzoate, would the reaction be faster or slower than the first nitration
Calculate concentrations of H30+ and the pH of each acidic solution. Since HCl is a monoprotic acid, the H30+ concentrations are equivalent to HCl. First do equation: (M con)(V con)=(M dil)(V dil)
When ethyl benzoate is heated in methanol containing a small amount of HCl, methyl benzoate is formed. Draw structural formulas for the first two intermediates in this reaction. Indicate the order of formation of the intermediates by drawing a 'Rea..
