Answer:
Because sugar has no ions in the solution
Explanation:
Pure water contains very few ions, so it does not conduct electricity very well. When table salt is dissolved in water, the solution conducts very well, because the solution contains ions. When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution.
In basic words the more ions in the solution there is a better chance to conduct electricity.
Answer: 3 Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same
Explanation:
Physical change mainly physical properties of a substance while the chemical changes remain unchanged. Once there is a change to the chemistry of the substance, this would be classified as a chemical change.
They are identical to the nucleus of the helium-4 atom. So the answer is helium atoms.
