When sodium fluoride dissolves and dissociates in water, a solvation sphere of water molecules forms around the ions. The solute
solvent interaction
and makes the beaker warm.
A)
absorbs energy from the surroundings
absorbs energy into the surroundings
releases energy into the surroundings
releases energy from the surroundings

Option C.

The solute solvent interaction making the beaker warm means it releases energy into the surrounding.

Explanation:

When sodium fluoride dissolves and dissociates in water, then this combo of solute and solvent will form the system. And the beaker in which both are contained is termed as the surrounding. So when the sodium fluoride dissociates in water, this means there occurs breakage in bonds of sodium flouride and as sodium fluoride is an ionic compound, so there will be breaking of ionic bonds. And ionic bonds releases more energy compared to any other kind of bond. So this release of energy from the system is given into the surrounding which inturn warms up the beaker in which the solute and solvent interacts.

Thus, the solute solvent interaction release energy into the surroundings and makes the beaker warm.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
