Answer:
His measurements will be more precise if he uses a graduated cylinder that measures to the nearest tenth of a mL.
Explanation:
I think the best answer is that the spinal fluid surrounds and protects the backbone. Also, it protects the brain from trauma. It acts as a shock absorber. It supplies nutrients to the nervous system tissue and removes waste products from the brain.
Solution :

<u>Explanation 1 </u>:
Spontaneity of the reaction is based on two factors :
-- the tendency to acquire a state of minimum energy
-- the energy of a system to acquire a maximum randomness.
Now, since there isn't much difference in the bond enthalpies of B-F and B-Cl. So, we can say the major driving factor is tendency to acquire a state of maximum randomness.
<u>Explanation 2 </u>:
A system containing the
B halides has a
than a system of
and
.
It has the same number of
, but more distinguishable kinds of
, hence, more microstates and higher entropy.
