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!
Answer:
The answer to your question is 18 neutrons
Explanation:
Data
Number of neutrons = ?
Atomic mass = 35
Three energy levels
seven valence electrons
Process
1.- We know that this element is on the third period (3 energy levels)
2.- We also know that this element is located on group 7A (it is a halogen)
3.- From the previous information, we conclude that this element is Chlorine.
4.- Chlorine has an atomic number of 17.
5.- The number of Neutrons = Atomic mass - atomic number
= 35 - 17
= 18
Answer:
percipitate or sedements from chemical reactions
Keeping the masses of the objects unchanged, if the distance between the objects is halved, then the magnitude of gravitational force between them will become. Hope this helps please mark brainliest :)
