If you start with 20 grams of hydrochloric acid, how many grams of sulfuric acid will be produced? Round to the nearest tenth. Don't forget the units. 2HCl + Na2SO4 - > 2NaCl + H2SO4
Weegy: according to the reaction 2 mol of HCl (mol-weight is 35.97 g/mol) will produce one mol of sulfuric acid (mol-weight is 98.079 g/mol), 20 grams of HCl is 20g/(35.97 g/mol) = 0,5560 mol, [ so we expect half of these for sulfuric acid 0,5560/2 = 0,2780 mol of H2SO4 or 0,2780 mol *98.079 g/mol = 27.3 grams. note: to achieve the reaction one has to use HCl in the vapor phase bubbling over sodium sulphate solution and cool the reaction ...

2C2H6 + 7O2 - > 4CO2 + 6H2O In the combustion of ethane, shown above, how many moles of carbon dioxide can be produced from 1.00 mole of ethane? A. 0.500 mole B. 1.00 mole C. 2.00 moles D. 4.00 moles
Weegy: The answer is , C. [ 2.00 moles ; It says - read coefficients - that 2 moles C2H6 requires 7 moles of O2 to make 4 moles of CO2 and 6 moles of H2O If 2 moles of C2H6 make 4 moles CO2, then logically 1 mole will make 2 moles of CO2 /question/index?qid=20090416125646AADPJ1v ] (More)
