The pH of a 0.0100 M sodium benzoate solution with a Kb of 1.5 × 10-¹⁰ is 5.91 (option B).

<h3>How to calculate pH?</h3>

The pH of a solution in chemistry refers to the notation expressing the acidity or alkalinity of a solution.

The pH is measured on a logarithmic scale of which 7 is neutral, lower values are more acid and higher values more alkaline.

The pH of a solution can be calculated using the following formula;

pH = - log {H+}

pH = - log {0.0100}

pH = 2

Therefore, the pH of a 0.0100 M sodium benzoate solution with a Kb of 1.5 × 10-¹⁰ is 5.91.

A and B are experiencing winter. The picture which isn't available here in this question is attached below.

Option C.

<h3><u>Explanation:</u></h3>

The earth is tilt by an angle of 23.2° to the vertical plane. This makes the seasonal variation of earth, because in some time of the year, the northern hemisphere faces the sun directly, experiencing summer and then southern hemisphere is away from summer experiencing winter and vice versa. The summer occurs when the place directly faces the sun. And the winter happens when the place obliquely faces the sun or doesn't face the sun at all.

Here in this diagram, we can see that the points A and B are the north pole and the part in northern hemisphere respectively which aren't facing the sun directly, whereas C and D are facing the sun. Thus the southern hemisphere is experiencing summer and the northern hemisphere the winter.

Do you think that the human being is the center of the universe?
Andrej [43]
I think that the sun is the center of the universe, not a human being. Everything revolves around the sun, not someone. U know when to sleep, when the time is, and when to wake up based on the sun. All the planets revolve around it. This is why I think the sun is the center of the universe, not a human being.
