A chemist is identifying an unknown solid substance that appears purple in color. Upon close inspection with a hand lens, she notices tiny grains in the substance. Some of the grains are blue; other grains are red. Based on this information, the substance is most likely a

a. Compound

b. Homogeneous Mixture

c. Pure substance

d. solution

e. heterogeneous mixture

heterogeneous mixture

Explanation:

A heterogeneous mixture simply means a mixture of two different substances. If two substances are the same, they are expected to have the same colour or appearance.

We were told in the question that the colour of the mixture appeared purple. On close examination, the sample was found to comprise of two different substances of different colours; blue and red.

If there are two substances of different colours present in the sample, it then follows that the sample is a heterogeneous mixture.

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.
