Answer:
1.25 M HCO₃⁻ / 1.25 M CO₃²⁻
Explanation:
Buffer capacity refers to the amount of a strong acid or base required per liter of the buffer to change its pH by one. This amount is directly related to the concentration of the conjugate acid-base pair in the buffer since the buffer pair neutralizes the strong acid or base.
Thus, the highest buffer capacity is found in the solution that has the highest concentration of the conjugate acid-base pair, which is 1.25 M HCO₃⁻ / 1.25 M CO₃²⁻

Answer:
John Dalton
Explanation:
John Dalton developed the concept tittle: Dalton Law of Partial Pressure.
The formula is: Pt = Pa + Pb + Pc...... Pn

Hi there
In order for an electron to jump into a higher energy state, it must first absorb energy (heat, light, etc).
When an electron goes back down to the ground state from the excited state, it emits energy usually in the form of a photon.
i hope this helps
