The rate of a chemical reaction can be raised by increasing the surface area of a solid reactant. This is done by cutting the substance into small pieces, or by grinding it into a powder.
C. they are equal
This is because it takes about the same amount of time for the moon to rotate around its axis that it does to rotate around the Earth.
Answer: Yes, 
is a strong acid.
acid = , conjugate base = 
, base = 
, conjugate acid = 
Explanation:
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
Yes is a strong acid as it completely dissociates in water to give 
ions.
For the given chemical equation:
Here, is loosing a proton, thus it is considered as an acid and after losing a proton, it forms which is a conjugate base.
And, is gaining a proton, thus it is considered as a base and after gaining a proton, it forms which is a conjugate acid.
Thus acid =
conjugate base =
base =
conjugate acid = .
D) Responds slowly
Good luck. It responds slower them the nervous system
