QuestionAI's chemistry problem solver is a middle school chemistry tutoring tool that summarises key chemical reactions and equations in real-time, featuring a robust learning system to empower even those with a weak foundation in chemistry.
You needn't fret over the elemental properties of the periodic table anymore. Here, you can effortlessly access chemical reactions and reaction principles corresponding to each element. Deductive reasoning from microscopic phenomena to discern the original structure of molecules and atoms is a research technique we staunchly champion.
- Franklin tests three solutions with a conductivity tester as shown in the picture. He tests a salt solution , a sugar solution, and an alcohol solution. Which solution, if any, conducts electricity, and why? A The salt solution conducts electricity because it has salt ions that carry electricity in water. B The sugar solution conducts electricity because it has sugar ions that carry electricity in water. C The alcohol solution conducts electricity because it has alcohol ions that carry electricity in water. D None of the solutions conduct electricity because they do not have ions that carry electricity in water.
- Can simple COVALENT compounds CONDUCT electricity? Around 50% can YES, always NO, never YES, but only as solids
