Calculate the ph of a buffer solution made from 0.10 m nh3 and 0.10 m nh4cl
salt. kb = 1.8 x 10-5

b. calculate the ph of the buffer in part a, after 12 ml of 0.20 m hcl is added to 125 ml
of the buffer in part a.

c. calculate the ph when 12 ml of 0.20 m hcl added to 125 ml of water. how does
the ph compare to the ph found in part b?

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

the answers are

c and c
