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⁺).

How many neutrons does element X have if its atomic number is 20 and its mass number is 82?

snow_tiger [21]

Protons = Atomic number
Protons + Neutrons = Mass Number
Protons = 20
Neutrons = Atomic number - Mass number
Neutrons = 82 - 20 = 62

Monochloroacetic acid (HC2H2ClO2) is a skin irritant that is used in "chemical peels" intended to remove the top layer of dead s

yaroslaw [1]

<u>Answer:</u> The pH of the solution is 1.703

<u>Explanation:</u>

We are given:

Concentration of monochloroacetic acid = 0.31 M

The chemical equation for the dissociation of monochloroacetic acid follows:

$HC_2H_2ClO_2\rightleftharpoons H^++C_2H_2ClO_2^-$

<u>Initial:</u> 0.31

<u>At eqllm:</u> 0.31-x x x

The expression of $K_a$ for above equation follows:

$K_a=\frac{[H^+][C_2H_2ClO_2^-}}{[HC_2H_2ClO_2]}$

We are given:

$K_a=1.35\times 10^{-3}$

Putting values in above equation follows:

$1.35\times 10^{-3}=\frac{x\times x}{(0.31-x)}\\\\x=-0.021,0.0198$

Neglecting the negative value of 'x' because concentration cannot be negative.

To calculate the pH of the solution, we use the equation:

$pH=-\log[H^+]$

$pH=-\log (0.0198)\\\\pH=1.703$

Hence, the pH of the solution is 1.703
