Which of the following balanced equations correctly represents the dissociation of K2SO4 in water?

K₂SO₄ - > 2K⁺ +SO₄²⁻

Explanation:

Dissociation of the ionic salts is defined as the separation of the cations and anions. This is facilitated in a polar solvent because in a polar solvent like water, the ions that get dissociated gets hydrated. This decrease their energy which is called the enthalpy of hydration. This stabilizes the ions and the whole solution.

In the case of potassium sulphate, the salt has potassium ions as the cations and sulphate ions as the anions. These ions get separated from each other which leads to formation of free potassium ions and sulphate ions.

The potassium ion being positively charged are stabilised by the oxygen part of the water and similarly, the sulphate being the anion, is supported by the hydrogen part of the water.

The reaction follows as K₂SO₄ - > 2K⁺ +SO₄²⁻

The answer to this problem is. 67

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.
