Chemistry
1 answer:
kirill [66]2 years ago
7 0

Answer:

To design a good scientific research, there is a few things you need. You need to have an experiment first of course . You need an hypothesis, a conclusion, and research. Question,analysis, and observation.

Explanation:

If this helps : In fifth grade we did a scientific experiment that we had to present. I chose to do if bananas turned bad first under UV light or sun rays and my hypothesis was that they would turn bad under the sun-rays. My conclusion was that they didn't. My observation was written down in a notebook of what I saw with each passing day. Research was what I looked up about of course how long bananas lasted and how long they didn't.

Hope it helps :)

how many H+ ions are in a solution with a pH of 2 and how many H+ ions are in a solution with a pH of 6?
LiRa [457]

Answer:

i) pH = 2

pH = -log(H+)

:- (H+) = 10^(-2)

:- (H+) = 0.01 M

ii) pH = 6

pH = -log(H+)

:- (H+) = 10^(-6)

:- (H+) = 0.000001 M

Explanation:

By definition: pH = -log(H+).

Given your pH, solve for the H+ using the the following log rule:

if a = (+/-) log (b) then

b = 10^((+/-) a).

Also remember unit of concentration is molar (M)
