(1) 5F2 + 2NH3 -> N2F4 + 6HF?

If you start with 25 g of F2, how many moles is this? How many moles NH3 will be needed. How many moles HF will be produced? How many grams of HF will be produced? And how many grams of N2F4 can be produced from those 25 g of F2?

(2) 6Na + N2 --->2Na3N. How many grams of product can be produced from 10 grams of Na?

(3) 2N2O5 ---> 4 NO2 +O2. When 25 grams of N2O5 is allowed to decompose, it was found that 10 grams of NO2 forms. What is the percent yield?

(4)Na3P + 3H2O ---> PH3 + 3NaOH. What is the theoretical yield of PH3 when 150 grams of Na3P is mixed with 250 grams of H2O? If the actual yield is 30 grams, what is the % yield?
