Answer:
20 mL
Explanation:
<em>The student should record 20 mL as the correct volume.</em>
The curved surface of a liquid that is usually observed in a buret is referred to as the meniscus. This meniscus is created as a result of the surface tension of the liquid against the walls of the buret. <u>Hence, in order to avoid errors due to parallax, the bottom of the meniscus should be read and not the top.</u>
Therefore, the correct volume that the student should record is 20 mL.

Answer:
656.25 mL
Explanation:
M1 = 0.40 M
M2 = 1.50 M
V2 = 175 mL
Plug those values into the equation:
M1V1 = M2V2
(0.40)V1 = (1.50)(175)
---> V1 = 656.25 mL
Termination
Additionally, curved arrows serve as a method of tracking changes in formal charge. Another technique to track changes in formal charge is with curved arrows: The atom at the tail will formally "lose" one electron because a pair of electrons are being given from it, increasing its charge by one.
<h3>What is radical mechanism ?</h3>
Three steps—initiation, propagation, and termination—define the radical chain mechanism. Energy must be provided for reaction to start, but once it does, it continues on its own.
- A free radical is referred to be a chemical entity that can exist independently and have an unpaired electron in its atomic orbital. The unpaired electron confers some common characteristics on all radicals.
