Answer:
Non metals are brittle solids.
Explanation:
The option A is correct,
Non metals are brittle solids.
It is the property of non metals. They can not be stretched into thin wire if stress is applied non metals brake down.
All other options are incorrect because,
B = Non metals are often malleable
It is the property of metals. Metals can be malleable into think sheets.
C = Non metals often conduct electricity.
It is the property of metals. Metals conduct electricity because of availability of free electrons.
D = Non metals are often ductile.
It is the property of metals. They can stretched into thin wire.
Here is your answer:
Your answer is A decreasing.
Reason: That's because when your turning into a solid your not moving and kinetic energy is the around of movement an object is moving.
Your answer is A.
the number of Valence electrons remains the same
For this question, I think it is the other way around. It is true that chloroacetic acid is stronger in strength than acetic acid. Acid strength is measured as the equilibrium constant of the reaction <span>HA -----> H+ + A-
</span><span> In acetic acid, the anion produced by dissociation is CH3-COO-; in chloroacetic acid it is CH2Cl-COO-. Comparing the two, in the first one the negative charge is taken up mostly by the two oxygen atoms. In the second there is also an electronegative chlorine atom nearby to draw more charge towards itself. Therefore, the charge is less concentrated in the chloroacetate ion than it is in the acetate ion, and, accordingly, chloroacetic acid is stronger than acetic acid. </span>
