Aye you have the same class as me bruh I need help on some chemistry qustions
Answer:
?
Explanation:
can you describe the question a little more please?
The concentration of hydroxide ion is 5 
10^
−
14 M.
<u>Explanation:</u>
Consider the equilibrium of this acid's dissociation,
H
C
l
O
4 ⇌ H
+ + C
l
O 4
-
Moreover, let's assume that H
C
l
O
4 is a strong acid and will fully dissociate.
Hence,
[
H
+
] = 0.20 M
Now, recall,
K
w = [
H
+
]
[
O
H
−
] = 1.0 10
^−
14
Hence,
⇒
[
O
H
−
] = K
w / [
H
+
] = 5 10^
−
14 M.
<h2>Answer : Option D) Heterogeneous mixture</h2><h3>Explanation : </h3>
A mixture in which particles are not evenly distributed and particles keep their unique properties are called as heterogeneous mixture.
Usually, in heterogeneous mixture the substances are not evenly distributed and they can be easily separated through any physical methods. Also the components retains their original/unique properties in the mixture. It usually contains various particles from different substances that are not uniformly distributed throughout the mixture.
The SI base units and their physical quantities are the metre for measurement of length, the kilogram for mass, the second for time, the ampere for electric current, the kelvin for temperature, the candela for luminous intensity, and the mole for amount of substance.
