The conjugate acid of ch3nh2 is ch3nh3+<span>.
</span>For example methylamine in water chemical reaction: 
CH₃NH₂(aq)+ H₂O(l) ⇌ CH₃NH₃⁺(aq) + OH⁻(aq).
According to  Bronsted-Lowry theory acid are donor of protons and bases are acceptors of protons (the hydrogen cation or H⁺). Methylamine (CH₃NH₂) is Bronsted base and it can accept proton and become conjugate acid (CH₃NH₃⁺).

Vein deposits are usually produced by _____. weathering density sorting hydrothermal solutions cementation
mart [117]

Answer:

Hydrothermal solutions

Explanation:

Vein deposits which cuts through rock layers are usually products of hydrothermal solutions.

Veins are rich ore deposits in which superheated water rich in dissolved minerals penetrated through a rock body and the minerals becomes precipitated and deposited in the process. Most veins have small width and a great length. Some occurs as veinlets depending on the nature of the weaknesses they trace out in a rock body.

Veins contains minerals such as gold, copper ore, rare earth metals. Most hydrothermal solutions contains minerals that are not compatible with the melt as rocks crystallize. They preferred to be carried with super heated water which deposits them seperately.
