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 :)

Answer:
1.2 mol/L
Explanation:
Molarity = mol solute/L solution
We can accept that
L solution = L water = 2.5 L.
Molarity = 3 mol/2.5 L = 1.2 mol/L
Answer:
Solubility range of KI in 500 grams of water at 20 degrees C is 700-740gm
Explanation:
Using the solubility curve of the solubility of KI with the given temperature
we infer from the graph that at 20 degrees Celsius the solubility of KI is 140-148 grams per 100 grams of water.
so for 500 grams of water the solubility of KI will be
= 140*5= 700gm to 148*5= 740
Solubility range of KI in 500 grams of water at 20 degrees C is 700-740gm
It takes <u><em>about a month</em></u> for the Moon to complete one revolution around the earth. It is much longer than 60 hours and much shorter than 365 days. <u><em>So the correct answer is C. 29.5 days. I think you made a typo, because the correct answer is 29.5 days not years.</em></u>
