1.5 M KNO3 - both solutions contain KNO3, but the one with higher concentration is 1.5 M, as 1.5 M > 1.0 M. 1.0 M also increases the boiling point, but not to as great an extent as 1.5 M does.
Answer:
Natural selection changes how well a species can survive in an environment.
Explanation:
I'm not the best at biology, but natural selection a term we use that's describes nature's way of choosing the strongest to survive. The species with the strongest adaptations will survive while the others will die off. For example, if a school of fish was forced to live in a colder habitat than usual, over many years some fish will adapt to that environment and be able to withstand it. But, some fish won't get those adaptations and be killed off. But, future generations will be born with that ability to withstand the cold environment and it would become normal. So, natural selection changes the way a species lives. Hope this helps
Rutherford and his colleagues were able to calculate the number of alpha particles which would be scattered onto any angle. And with the agreement of these calculations up to a certain large angle where they got significant deviations.
<span>NaOH = 19.35 - 0.15
= 19.2 mL
19.2 mL x 0.317 M = 6.086 millimoles NaOH
6.086 mmol NaOH neutralized 6.086 mmol acetic acid
6.086 mmol acetic acid / 25.0 mL = 0.2435 mmol/mL
= 0.2435 mol/L
Acetic acid was 0.2435 M</span>
Answer:
atmosphere
Explanation:
All living organism cannot live without atmosphere. Atmosphere is the layer that surrounds the earth surface. It has a lot of gasses e.g oxygen, nitrogen, carbon dioxide etcetera
