A. CI, Br
Explanation:
Different kinds of atoms bind their valence electrons with various amounts of energy. In order to remove the valence electrons, enough energy must be available.
The amount of energy required for the removal of an electron is the ionization energy or ionization potential.
The ionization energy depends on:
- Nuclear charge
- Atomic radius
- Sublevel accomodating the electron to be removed.
- Special stability of half or fully filled sublevels.
Across a period, the ionization energy increases.
Down a group ionization energy decreases due to increasing atomic radii.
Cl and Br are in the same periodic group. Cl is element number 2 and Br is element 3 in the group of the halogens.
Therefore, Cl will have a higher ionization energy compared to Br.

Answer:
Catalase
Explanation:
These reactive oxygen specie or free radicals that cause damage or injury to cells also lead to oxidative stress if unchecked by antioxidants. As suggested in the question, there are several enzymes that act as antioxidants in mitigating the effects of these reactive oxygen specie or free radicals. These enzymes include catalase, superoxide dismutase and glutathiones (such as glutathione s-transferase).
The enzyme that however prevents the accumulation of hydrogen peroxide (H₂O₂) in the peroxisome is catalase. Catalase is an enzyme that is present in the peroxisome; it (catalase) detoxifies/acts on H₂O₂, converting it (H₂O₂) into water and oxygen.
Answer:
less, decreases
Explanation:
When the pressure of an atmosphere occurs because of the force exerted so at the time of the higher altitudes, the air mass i.e. above the earth should be less as the air is attracted towards surface of an earth because of the gravity and air contains the mass that shows near the surface area so automatically the air density reduced due to which the mass also decreased
Answer:
The answer is melting and freezing point.
Explanation:
Chemical equation represents a redox reaction :
2Li + MgCl₂ → 2LiCl + Mg
<h3>Further explanation</h3>
The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number
Reaction
2Li + MgCl₂ → 2LiCl + Mg
Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.
