Answer:

Potassium chloride

Explanation:

A solution is formed by a solvent and one or more solutes.

The solvent is the species that is in major proportion and usually defines the state of aggregation of the solution, while the solute/s is/are in minor proportion.

Also, water is known as the universal solvent, so in any solution containing water, it is considered as the solvent.

Then, in an aqueous solution of potassium chloride the solute is potassium chloride.

Lady bird [3.3K]

Answer:

Energy is neither created nor destroyed.

Explanation:

The law of conservation of energy states that energy can neither be created nor be destroyed. The total energy of an isolated system remains conserved. It never gets 0. It changes from one form of energy to other but never vanishes.

Hence, the correct option is (d) "Energy is neither created nor destroyed"

What must break in order for water to change from solid to liquid to gas? what must break in order for water to change from soli

Step2247 [10]

Answer:

hydrogen bonds between water molecules

Explanation:

The hydrogen bonds between water molecules conditions the bulk of its physical property most especially its relatively high boiling point. The hydrogen bond results from the attraction between the oxygen of a water molecule and the hydrogen of another water molecule. The more electronegative oxygen atom causes a distortion and the attraction leads to a strong intermolecular bond between atoms of the water molecules.

Hydrogen bond is a very strong bond and it is responsible for the physical properties of water.
