if a substance is solid at room temperature, has a crystalline structure, dissolves easily in water, and conducts electricity well, then it likely contains ionic bonds. otherwise, it likely contains covalent bonds. was the hypothesis, repeated above, completely supported? justify your answers.
Answer
Answer:
No, the hypothesis is not completely supported.
Brief Explanations:
There are substances like some metals (e.g., mercury is liquid at room - temperature) that conduct electricity well but don't fit all criteria. Also, there are covalent - network solids (e.g., diamond) with a crystalline structure but are not soluble in water and have different bonding characteristics. So, the simple binary classification in the hypothesis is an over - generalization.
