(100 POINTS PLS ANSWER) How are mixtures and solutions different? (1) Unlike a solution, a mixture can dissolve completely in a liquid because the properties of the ingredients change.

(2) Unlike a solution, a mixture is unable to change states of matter from a solid to a liquid or gas.

(3) Unlike a solution, a mixture can easily be separated and each ingredient keeps its physical properties.

(4) Unlike a solution, a mixture has density and will always sink in a liquid because mixtures lack buoyancy.

Your answer is the second one or choice B

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
