8 0

Answer:

Option (C) 3

Explanation:

The pH scale is a scale that ranges from 0 to 14. The pH reading has various notifications. These notifications are as follow:

1. If the pH reads between 0 and 6, then the solution is acidic.

2. If the pH reads 7, then the solution is neutral.

3. If the pH reads between 8 and 14, then the solution is basic.

With the above information, option C is the correct answer to the question.

never [62]

Answer:

k ≈ 9,56x10³ s⁻¹

Explanation:

It is possible to solve this question using Arrhenius formula:

$ln\frac{k2}{k1} = \frac{-Ea}{R} (\frac{1}{T2} -\frac{1}{T1} )$
