using the balanced equation 2NACL(s) + H2SO4(aq) ---> 2HCl(aq) + Na2SO4(aq). A.) If 20. g of NaCl are used, how many grams of H2SO4 are required for complete reaction? B.) if 20. g or NaCl are used and only 5.6 g of HCl are isolated, what is the percent yield of HCl? C.) If only 5.6 g of HCl are obtained, how many grams of Na2SO4 must also have been formed?
If the pistons in the four cylinders are each displaced with a pressure of 1.52 kbar and each cylinder is ignited once per second, how much work can the engine do in 1.00 minutes?
Next calculate molar internal energy and molar heat capacity assuming vibrational energy levels are not significantly populated at 298 K and do not contribute to molar heat capacity and molar internal energy. Calculate percent error for each molar..
