Hello!
First, HNO₃ dissociates in the following way:
HNO₃(aq) → H⁺(aq) + NO₃⁻(aq)
Next, there is a neutralization reaction with Methylamine:
H⁺(aq) + CH₃NH₂(aq) → CH₃NH₃⁺(aq)
Finally, the formed methylammonium ion weakly dissociates in the following way:
CH₃NH₃⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq) + CH₃NH₂ (aq)
From this sequence of reactions, we can see that the resulting solution would be slightly more acidic than the initial one, as the buffer solution resists the addition of strong acid.
Have a nice day!
The answer is Base.

<span>pH scale is used to determine how acidic, basic or neutral a solution is.
pH can be calculated using the Hydrogen ion concentration.
pH is calculated using the following formula
pH = -log [H</span>⁺<span>]
[H</span>⁺<span>] can be calculated knowing the pH
[H</span>⁺<span>] = antilog(-pH)
[H</span>⁺<span>] = 1.32 x 10</span>⁻¹⁰<span> M</span>
Answer: E
Hope this helped :)
Aluminum has a molar mass of 27. So one mole of aluminum is 27grams
