Salt and sugar are poured into a glass of water and stirred. slowly, the salt and sugar crystals become harder to see and then cannot be seen at all. what happened to the salt and sugar?
group of answer choices
they dissolved into the water, forming a mixture.
they reacted with the water, forming a compound.
they combined with the water, forming an element.
they evaporated from the water, forming a solid.

They dissolved into the water, forming a mixture.

Explanation:

The salt is sodium chloride (NaCl) and the sugar is a dissacharide which contains many hydroxyl  groups (-OH). Both of them are very soluble in water, but they will not start a chemical reaction between themselves.

Dissolving them in water will form a mixture of chloride ions (Cl⁻), sodium ions (Na⁻) and sugar molecules.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
