Answer:
True
Explanation:
The amount of Hydrogen ion and hydroxide ion determines the acidity or alkalinity of an aqueous solution.
The higher the hydrogen ion content the higher the acidity of the solution. The increase in the amount of the hydrogen ion brings about decrease in the pH scale. The pH scale of about 0 - 2 has a very high hydrogen ion contents and as the Hydrogen ion decreases the pH value increases.
The higher the hydroxide ion contents the higher the alkalinity . The increase in the amount of hydroxide ion brings about increase in the pH value. The pH value of 12 - 14 depicts very strong alkalinity content. As the hydroxide ion increases the pH value increases.
If the hydroxide ion and hydrogen ions are of equal proportion the solution becomes neutral. The pH value for neutrality is 7.
I think it is around 95.211

Answer:
C. A Spring Scale
Explanation:
Using process of elimination, we can quickly decide that a stopwatch and a ruler will not be useful in measuring the force. This leaves us with either the spring scale or a balance scale. A balance scale is used to compare two weights, so this is eliminated. That leaves us with a spring scale. This is because we can attached the spring scale to the car and when we let it go, we can record the force. I hope this helps!
