Physical change does not make a new chemical/object. A chemical change does.
Chemical Change example: Combining liquid and liquid to create a new substance
Given that,
The concentration of
TRIS = 0.30 M
The concentration of
TRIS+ = 0.60 M
Kb = 1.2 x 10^-6
pKb = -log Kb = - log
(1.2 x 10^-6) = 5.920
Now, by using the
Hendersonn equation,
pH = pKa + log
TRIS+/TRIS = 5.920 + log (0.60/0.30) = 6.221
<span>pOH=14-pH=14-6.221 =
7.779</span>
Your answer would be, Sugar is the solute, and water is the solvent. a solution is the mixture of two, or more substances.
Hope that helps!!!
Answer:
c
Explanation:
we cannot say that either will die out, because we dont know the conditions. but we know that both sides out the mountian arent exactly the same, so we know they will evolve to adapt and grow with what they have
The correct answer is A
Filter out the sand, because the sand does not dissolve in water, and then evaporate water from sugar solution
