Answer 8

@iheartfood WTH!!! lol want to add more questions?

Answer 9

ur right its D

Answer 10

Answer 14

So the answer is A? Not C? if so, how'd u get A?

and @nincompoop what do you mean? haha

Answer 15

logarithm

Answer 16

u apply log to the option A and see that you get the answer Ph=5.6

Answer 17

you got this from your biology, right?

Answer 18

okay, so the answer to 3 is definitely A. 5.0 × 10^-5 then?

and @nincompoop its chem :)

Answer 19

log5.0 × 10^-5
=-(-5)+log 5
=5.6
pH=-log[H+]

Answer 20

z=logX^Y
z=ylogX

Answer 21

ohh thats how you do that? thats it? :O

Answer 22

yaaa some times you have to think reverse man LOL:)
