Use the information about igneous rocks A–D to classify each one as intrusive or extrusive and basaltic or granitic. Fill in the chart with A, B, C, or D. Rock A—dark-colored large grains Rock B—large crystals, high percentage of silica Rock C—fine-grained texture, light-colored Rock D—from Hawaiian volcano area, no visible crystals Extrusive Intrusive Basaltic 1. 2. Granitic 3. 4.

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.
