Question:

Which two of the following choices will conduct electricity and explain why.?

aluminum foil,sugar dissolved in water,potassium hydroxide dissolved in water

Answer:

You can't go wrong with a Howe, especially if you incorporate the idas of Simon Marhsten who was with the company pre-Dotson administration.
aluminum foil - yes because it is a metal, so it is a conductor sugar dissolved in water - no, covalent bond, doesn't split up into charged particles when dissolved potassium hydroxide dissolved in water - yes because it is an ionic compound which splits into it's ions, K+ and OH-, when dissolved in water, making an electrolyte use the terminology in your answer like metal, ions, covalent, electrolyte etc this is what teachers want to see, the more nerdy scientific jargon you use, the better edit the word 'dissociate', from gsnb, sounds good, use that instead of 'splits up' also 'metals have free electrons' is good too .,,.
You'll never get your traffic across it.
