For the neutralization reaction between methylamine and acetic acid, draw curved arrows to indicate the direction of electron flow. Draw curved arrows to show the movement of electrons in this step of the mechanism.

This is required answer.

Explanation:

Given that,

The neutralization reaction between methylamine and acetic acid

We know that,

According to proton theory of acid and base,

An acid is a substance which denotes the hydrogen as proton.

Base is a substance which accept the proton.

We need to draw curved arrows to indicate the direction of electron flow

According to diagram,

Diagram shows the movement of electrons in this step of the mechanism.

Hence, This is required answer.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.
