Answer:
The rate of evaporation is directly proportional to Temperature because as the temperature increases, the energy of the particles increases. Due to increases in energy, particles start to break intermolecular bonding and evaporates.
Based on the dilution formula, 0.1 mL of the stock solution of the enzyme is required to prepare a 50-fold diluted enzyme in 0.01 M HCl.
<h3>How can 50-fold dilution of the enzyme be done?</h3>
The 50-fold dilution of the stock enzyme solution can be done by using the dilution formula to determine the given volume of the stock solution required.
The dilution formula is given below:
where:
- C1 = Initial concentration of enzyme
- C2 = Final concentration of enzyme
- V1 = Initial volume
- V2 = Final volume
From the given data for the enzyme dilution;
C1 = 1
C2 = 1/50 = 0.02
V1 = x
V2 = 5 ml
Making V1 subject of formula in the dilution formula:
V1 = C2V2/C1
V1 = 0.02 * 5/1 = 0.1 mL
Therefore, 0.1 mL of the stock solution of the enzyme is required to prepare a 50-fold diluted enzyme in 0.01 M HCl.

Answer:
Explanation:
Oppositely charged particles attract each other, while like particles repel one another. Electrons are kept in the orbit around the nucleus by the electromagnetic force, because the nucleus in the center of the atom is positively charged and attracts the negatively charged electrons.
Data:
![[ H_{3} O] = 1.0*10^{-12}](https://tex.z-dn.net/?f=%5B%20H_%7B3%7D%20O%5D%20%3D%201.0%2A10%5E%7B-12%7D)
<span>The logarithm of number 1 on any basis will always be equal to 0, therefore:
Log10 (1) = 0

Solving:
![pH = - log[ H_{3} O^+]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%5B%20H_%7B3%7D%20O%5E%2B%5D)
