I believe your answer is B.
Answer:
The correct answer is c add more HCO3- by adding NaHCO3.
Explanation:
The reaction mentioned in the question is carried out by bicarbonate buffer system of our body to maintain the normal acid base balance.
Now concentration of the reactant (H2C03) is decreased then NaHCO3 should be added which undergo breakdown to release bicarbonate ions(HCO3-).
The released bicarbonate ions then reacts with H+ to form Carbonic acid(H2CO3).Thus homeostasis of H2CO3 is maintained.
The answer is (3) 3. The outer shell of an atom is called valence shell. And the ground state is the lowest energy state of an atom. Aluminum has a electron distribution of 2, 8, 3. So the outer shell has 3 electrons.
