<h3>What is
Fluorine?</h3>
The chemical element fluorine has an atomic number of 9 and the symbol F. The lightest halogen, it is an extremely poisonous, pale yellow diatomic gas under normal conditions. It is exceedingly reactive and, as the most electronegative element, reacts with all other elements with the exception of argon, neon, and helium.
Fluorine is the 24th most abundant element overall and the 13th most abundant on Earth. In order to decrease the melting temperatures of metal ores for smelting, fluorite, the main mineral source of fluorine, was added. The Latin verb fluo, which means "flow," gave the mineral its name. Fluorite was first described in 1529.

4 moles
Explanation:
Given parameters:
number of moles of reacting NO = 24moles
Equation of the reaction:
4C₃H₆ + 6NO ⇒ 4C₃H₃N + H₂O + N₂
Solution:
The moles is synonymous the quantity of matter that contains the avogadro's number of particles.
To solve this problem, we must ensure that the given equation is balanced by simply inspecting.
The equation is balanced by inspection.
From the balanced equation;
6 moles of NO reacted to produce 1 mole of nitrogen gas
24 moles of NO will therefore produce 
= 4 moles

Answer:
<h3>The answer is 2.75 × 10²⁴ molecules</h3>
Explanation:
The number of molecules of CO2 can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 4.56 × 6.02 × 10²³
We have the final answer as
<h3>2.75 × 10²⁴ molecules</h3>
Hope this helps you
Answer:
a. participate in proton transfer - His
b. acts as a nucleophile - Ser
Explanation:
Enzymes are regulated because they are proteins. They are categorize based on how they catalyze. Heat weakens and inactivates the enzymes because of non covalent interaction. His amino acid participate in proton transfer because it is able to act as an acid as well as a base while Ser amino acid can act as nucleophile.
