29. What mass in grams of sodium hydroxide is produced if 20.0 g of sodium metal reacts with excess water according to the chemical equation 2Na(s)+2H20(l)=2NaOH(aq)+Hs(g)?

30. What mass in grams of 1-chloropropane (C3H7Cl) is produced if 400. g of propane react with excess chlorine gas according to the equation C3H8+Cl2=C3H7Cl+HCl?

31. How many grams of ammonium sulfate can be produced if 30.0 mol of H2SO4 react with excess chlorine gas according to the equation 2NH3(aq)+H2SO4(aq)=(NH4)2SO4(aq)?

32. How many moles of Ag can be produced if 350. g of Cu are reacted with excess AgNO3 according to the equation Cu(s)+2AgNO3(aq)=2Ag(s) +Cu(NO3)2(aq)?

33. What mass in grams of hydrogen gas is produced if 20.0 mol of Zn are added to excess hydrochloric acid according to the equation Zn(s)+2HCl(aq)=ZnCl2(aq)+H2( )?

    you should really show what you did (make an attempt), people will not do all of your homework for you here.

    It is best for you to post one question per post. ALSO, it is best for you to show what you CAN do and tell us what you CAN'T do (especially what you don't understand how to do). After you have done this someone will be glad to help you finish.
