Answer:
The pH of the substance is 4,06.
Explanation:
The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as:
pH = -log (H +)
pH= -log (8.8x10^-5)
<em>pH=4,06</em>
The answer is- The energy of 1 L water at temperature 347.78 °C have more energy as 1 L of water at temperature 65°C.
Heat is a type of energy that causes a person's body to feel hot or cold.
While the temperature of an object is a parameter that indicates how hot or cold the object is.
How is the temperature in degree Fahrenheit converted to degree celsius?
- To convert the temperature in Fahrenheit to Celsius, subtract 32 and multiply by 5/9.
°![C =( ^0F -32) * \frac{5}{9}](https://tex.z-dn.net/?f=C%20%3D%28%20%5E0F%20-32%29%20%2A%20%5Cfrac%7B5%7D%7B9%7D)
- Now, heat is a form of energy that flows from hotter object to colder object and temperature indicates whether the object is hot or cold by measuring its average kinetic energy.
- Now, the given temperature of 1 L water is 658 °F. This temperature in degree celsius is calculated as-
°C ![= (658 F-32) *\frac{5}{9} = 347.78 \° C](https://tex.z-dn.net/?f=%3D%20%28658%20F-32%29%20%2A%5Cfrac%7B5%7D%7B9%7D%20%3D%20347.78%20%5C%C2%B0%20C)
- Now, higher the temperature, higher is the energy of water. Thus, the energy of 1 L water at 347.78 °C have more energy as 1 L of water at 65°C.

Your answer is D. 8
16 = 2^4
72 = 2^3*3^2
So you'll choose 2^3 = 8
When placed in a container, the heaviest (most dense) will sink to the bottom and the lightest (least dense) will rise to the top.
Therefore, Gasoline would rise to the top.
