The collision of two plates causes the formation of fold mountains.
<u>Answer:</u> The equilibrium reaction of trimethylamine with water is written below.
<u>Explanation:</u>
According to the Bronsted-Lowry conjugate acid-base theory:
- An acid is defined as a substance which looses or donates protons and thus forming conjugate base.
- A base is defined as a substance which accepts protons and thus forming conjugate acid.
The equilibrium reaction for the reaction of trimethylamine acting as a weak base in water follows:

Hence, the equilibrium reaction of trimethylamine with water is written above.
Answer:
16.1 s
Explanation:
The reaction, A → Products, follows first order kinetics.
So,
ln[A] = ln[A]o - kt
Where;
[A] = concentration at time= t
[A]o = initial concentration
k= rate constant
t = time taken
ln(0.205) = ln(0.850) - 0.0882t
ln(0.205) - ln(0.850) = - 0.0882t
-1.5847 - (-0.1625) = - 0.0882t
-1.5847 + 0.1625 = - 0.0882t
-1.4222 = - 0.0882t
t = -1.4222/- 0.0882
t = 16.1 s
