2.Dinitrogen tetrafluoride N2F4, can be produced by the reaction NH3 with
F2
2NH3(g) + 5F2(g) N2F4(g) + 6HF(g)
a. If 4.00 g of NH3 and 14.0 g of F2 are
allowed to react. Which is the limiting
reagent?
b. How many grams of N2F4 and HF are
produced?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
