Answer
Associate of Science
Explanation
An Associate of Science gears a students towards math and science related careers. It requires the student to attend more science and math classes. STEM degrees are of high demand in many industries. Computing and engineering degrees program are in greatest demand and students have high opportunities of acquiring scholarships for study.
Explanation:
We know that relation between and is as follows.
= 14
As it is given that is 8.18. Therefore, calculate the value of as follows.
= 14
= 14
= 14 - 8.18
= 5.82
Similarly, as value of pH is given as 7.18. Therefore, value of pOH will be as follows.
pH + pOH = 14
7.18 + pOH = 14
pOH = 6.82
Let us take that B represents the enzyme. Hence, its reaction with proton will be as follows.
(protonated active enzyme)
Hence, pOH =
6.82 = 5.82 +
= 10
Therefore, percentage of active enzyme = % =
% = 90.9%
Thus, we can conclude that 90.9% is the percentage of the enzyme which is active in a buffer at pH 7.18.
Answer:
mass of Cu = 26,34615g
Explanation:
The equation for reaction is
Cu + 2 AgNO3 ---> Cu(NO3)2 + 2 Ag
1mol 2mol 1mol 2mol
mass of Ag that reacted = 89.5g
molar mass of Ag =107.86h/mol
number of moles = mass/molar mass
number of moles of Ag = 89.5/107.86
=0.8298moles
from the stoichoimetric relation;
1mol of Cu reacted to produce 2moles of Ag;
hence 0.8298moles of Ag produce would require; 0.8298/2 moles of Cu to react
=0.4149moles of Cu
mass of Cu = moles of Cu * molar mass of Cu
molar mass(Cu) = 63.5g
mass of Cu = 0.4149 * 63.5
mass of Cu = 26,34615g
