By reacting soda solvay containing 91% sodium carbonate, with an excess of 2 molar hydrochloric acid solution, 49.2 cubic decimetres of co2 at 29ºc and a pressure of one atmosphere (in addition to h2o and nacl) are obtained, with a performance of 86%. a) calculate the mass of solvay soda used. b) the mass of h2o formed. c) the amount of moles of co2 obtained. d) the minimum volume of the hcl solution to be used."

What type of reaction is zn + cucl2 → cu + zncl2?

Given that 1 mi = 1760 yd, determine what conver- sion factor is appropriate to convert 1849 yd to miles; to convert 2.781 mi to yards.

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
