Statement B correctly describes the situation.

Answer from: mckinzirauch9

The correct answer is option B.

Explanation:

pH is defined as negative logarithm of hydrogen ion concentration. It is basically defined as the power of hydrogen ions in a solution. It ranges to the scale of 1-14. The solutions are divided into 3 categories on the basis of the pH range:

If the pH of the solution ranges from 1 to 6.9, the solution is said to be acidic. Less the pH, more the acidity of the solution. If the pH of the solution ranges from 7.1 to 14, the solution is said to be basic. More the pH, more the acidity of the solution.If the pH of the solution is 7, the solution is said to be a neutral solution.

We are given:

pH of vinegar = 5

pH of rainwater = 6

As, the pH of both the solutions is less than 7. Thus, both the solutions are acidic in nature and also pH of vinegar is less, so this solution will be more acidic in nature.

Hence, the correct answer is Option B.

Mass is the amount of matter in an object. weight is the measurement of the pull of gravity on an object. say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165) now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon. however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant. in conclusion it is possible for your weight to change as your mass remains constant.
