Asked by Emily

Can someone check and make sure I'm doing these problems right? Thanks so much!!

1. N2 + 3H2 ==> 2NH3 : How many moles of hydrogen are needed to completely react with two moles of nitrogen?

==> I got 6 moles.

3. Zn + 2HCl ==> ZnCl2 + H2 : How many moles of hydrogen are produced from the reaction of three moles of zinc with an excess of hydrochloric acid?

==> I got 3 moles.

5. K3PO4 + Al(NO3)3 ==> 3KNO3 + AlPO4 : How many moles of potassium nitrate are produced when two moles of potassium phosphate react with two moles of aluminum nitrate?

==> I got 6 moles.

------------------------------------------------------------------------------

These problems are mass-mass problems:

1. 2KClO3 ==> 2KCl + 3O2 : How many grams of potassium chloride are produced if 25 g of potassium chlorate decompose?

==> I got 15.16 grams.

2. N2 + 3H2 ==> 2NH3 : How many grams of hydrogen are necessary to react completely with 50 g of nitrogen in the above reaction?

==> I got 10.71 g.
