Answer:
The frequency of wave is 0.125 Hz.
Explanation:
Frequency:
"It is an event repeat itself in a given period of time"
The unit of frequency is the Hz . If time is measured in seconds then frequency will be in Hz. Hz is equal to the per second.
Formula:
f = 1/ T
f = 1/ 8 sec
f = 0.125 Hz
8miles in 2 hours. Let's find how many she did on average in one hour.
8/2 = 4miles per hour.
No
Explanation:
Not all organic substances are soluble in water and will not conduct electricity. Only polar organic compounds are soluble in water and will conduct electricity.
- The general rule of solubility is that like dissolves likes.
- Polar compounds will only dissolve other polar compounds too. Water is a polar solvent.
- Non-polar compounds will only dissolve in non-polar compounds too.
- Since water is a polar organic compound, only polar organic compounds will dissolve in it.
- Not all organic compounds are polar.
- When a compound dissolves in water, it produces ions that makes it able to conduct electricity.
- Fats and oil are insoluble in water

Answer:
the pH of the solution expresses the concentration of hydrogen ion in the solution. By measuring the pH value of a solution helps us to define the acidity or basicity of the solution. If the pH value in the pH scale is greater than 7 then the solution is basic

Answer:
3.52 moles are equal to 21.2 ×10²³ molecules
Explanation:
Given data:
Number of moles of oxygen fluoride = 3.52 mol
Number of molecules = ?
Solution:
The given problem will solve by using Avogadro number.
1 mole contain 6.022×10²³ molecules
3.52 mol ×6.022×10²³ molecules / 1 mol
21.2 ×10²³ molecules
Thus, 3.52 moles are equal to 21.2 ×10²³ molecules .
