It is harder to remove an electron from fluorine than from carbon because the size of the nuclear charge in fluorine is larger than that of carbon.
The energy required to remove an electron from an atom is called ionization energy.
The ionization energy largely depends on the size of the nuclear charge. The larger the size of the nuclear charge, the higher the ionization energy because it will be more difficult to remove an electron from the atom owing to increased electrostatic attraction between the nucleus and orbital electrons.
Since fluorine has a higher size of the nuclear charge than carbon. More energy is required to remove an electron from fluorine than from carbon leading to the observation that; it is harder to remove an electron from fluorine than from carbon.

Answer:
<h2>0.15 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
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
We have the final answer as
<h3>0.15 moles</h3>
Hope this helps you
Answer:
D (or E If properly listed to include the active site option)
Explanation:
A. Is true
Enzymes are organically biochemical catalyst and thus they can speed up the rate of chemical reaction in the body
B is true
They are catalysts as said earlier
C is true
They have active sites. An enzyme does not act on all substrates. They have particular group on which they can act. For example, we have carbohydrates enzymes that act on carbohydrates substrate only. This enzymes have no business acting on a protein substrate.
D. Enzymes are proteins
One of the important characteristics of enzymes is that they are protenious in nature
E. This is wrong. Enzymes like any over catalyst are not consumed in the course of the biochemical reaction
Answer:
Correct option is answer a) SCl2
