It’s called neutralization. The alkali has neutralized the acid by taking away the H+ ions and then turning them into water.
<u>Answer:</u> The concentration of acetic acid in the vinegar is
<u>Explanation:</u>
To calculate the pH of the solution, we use the equation:
We are given:
pH = 2.95
Putting values in above equation, we get:
The chemical equation for the ionization of acetic acid follows:
The expression of for above equation follows:
We are given:
Putting values in above expression, we get:
So, the concentration of acetic acid =
Hence, the concentration of acetic acid in the vinegar is
Answer : The correct option is, B) 200 N to the left
Explanation :
If the two forces are acting on an object in the opposite directions and they do not exactly cancel each other then the net force is calculated by the difference in the forces.
The force act on an object in the left side are greater than the right side. So, the net force is 200 N to the left.
Therefore, the correct option is, B) 200 N to the left
