The identity of the unknown compound is Urea from the Table# given. The reason for this identification will further be discussed below.
<h3>What is melting point?</h3>
Melting point can be defined as the point at which a substance changes from a solid phase or state to a liquid state
When two substances of different melting points are added together, the total melting point obtained is usually depressed.
From the table,
- When urea and benzoic acid is added the melting point range becomes = 117-120
- When urea and Cinnamic acid is added the melting point range becomes= 100-125, and both of which is lower than the individual melting points.
Therefore, the identity of the unknown compound is Urea from the Table# given.

#SPJ1
The answer is True, those items are essential for working with hazardous chemicals.
Answer:
It effects all of the cellular respiration process
Explanation:
It inhibits the Glycolysis. It replaces the phosphate groups that is needed for making Pyruvate and ATP.
Answer:
See Explanation
Explanation:
Let us recall that;
[H^+] [OH^-] = 1 * 10^-14
Where;
[OH^-] = 1 x 10^-11
Then;
[H^+] = 1 * 10^-14/1 x 10^-11
[H^+] = 1 * 10^-3
pH = -log [H^+]
pH = -log(1 * 10^-3)
pH = 3
Also;
pH + pOH = 14
pOH = 14 - pH
pOH = 14 -3
pOH = 11
