Question
ding Exam Form) moletule At standard pressure, a certain compound has a low boiling point and is insoluble in water At STP, this compound most likely exists as 7. (1) ionic crystals (2) metallic crystals (3) nonpolar molecules (4) polar molecules 8. When NaCI(s) is dissolved in H2O (), the sodium ion is attracted to the water molecules Jo (1) (2) (3) (4) negative end, which is hydrogen negative end, which is oxygen positive end, which is hydrogen positive end, which is oxygen 9. In a nonpolar covalent bond, electrons are located in a mobile "sea" shared by many ions transferred from one atom to another shared equally by two atoms shared unequally by two atoms (1) (2) (3) (4) Which formula represents an ionic compound? 10.Explanation / Answer
7. Option 3, since it is insoluble in water means that it is non polar.
8. Option 2, negative end of oxygen. Since NaCl split into Na+ & Cl-.
9. Option 3, shared equally by two atoms since it is non polar covalent bond.
