Question 1:

For the reaction given below, answer the following questions:

S(s) + 4HNO3(s) SO2(g) + 4NO2() + 2H2O(g) a) Because the reaction is very smelly you want to make sure you make 3.25g of SO2. How much solid sulfur do you need to make this?

b) Calculate theoretical yield of the reaction.

c) If the yield of the reaction is 59%, how much of the SO2 will you make?

d) If you perfect the reaction the yield can be 75%. How much sulfur do you need to add to make the required 3.25g?

question 2

: a) Balance the equations given below (phase labels omitted for clarity): i) Na2P2N3 + F2 NaF + NaP4N6
