Question 3 options:
True
False
Question 4 (1 point)
What adding pressure to a system that has more molecules on the reactants side, like the one below what happens to the equilibrium?
N2 + 3H2 <-> 2NH3
Question 4 options:
Adding pressure will cause the forward reaction to occur creating more NH3
Adding pressure will cause the reverse reaction to occur creating more reactants
Adding pressure will not effect equilibrium
Adding pressure will cause the forward reaction to occur creating more H2.
Question 5 (1 point)
Match the following items correctly.
Question 5 options:
Is used to create ammonia from hydrogen and nitrogen.
French-Italian chemist who worked in the late nineteenth and early twentieth centuries.

Answer asap need to be answered 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.
