Answer:
A. 2,3 BPG
Explanation:
2,3-bisphosphoglycerate (BPG), otherwise known as 2,3-DPG, enables the transition of hemoglobin from a very high-oxygen-affinity state to a reduced-oxygen-affinity state.
Tissues hemoglobin oxygen affinity is reduced by numerous physiological factors including.
1. Temperature Increased,
2. Carbon dioxide,
3. Acid and
4. 2,3-Bisphosphoglycerate (2,3-BPG)
all of which can contribute to decrease the oxygen affinity of hemoglobin which favours unloading and increased oxygen availability to our body cells.
I think you don’t need the help anymore so can I just take these real quick ?

The mass of sodium chloride : 3.5 g
<h3>Further explanation</h3>
Given
Reaction :
2.5g of sodium sulphate + 4.5g of barium chloride ⇒ 3.5g of barium sulphate + sodium chloride
Required
The mass of sodium chloride
Solution
Conservation of mass applies to a closed system, <em>where the masses before and after the reaction are the same</em>
From the reaction :
mass of reactants = 2.5 g + 4.5 g = 7.0 g
mass of products = 3.5 g + mass of sodium chloride
mass of reactants = mass of products
7.0 g = 3.5 g + mass of sodium chloride
mass of sodium chloride = 7 g - 3.5 g =3.5 g

Answer :
1. It will shift left ( as heat is added)
2. It will shift right ( as it cooled down)
Explanation :
For an exothermic reaction, heat is a product. Therefore, increasing the temperature will shift the equilibrium to the left, while decreasing the temperature will shift the equilibrium to the right.
