When you combine sulfuric acid with sugar, you will obtain a reaction. Watch the video segment "Candy Shop" with the sound off. This video segment shows the reaction between sulfuric acid and sugar. Describe when you know that the initial chemical reaction has taken place, and describe further changes and how you know that they are occurring.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

the answer is barium and copper bromide

wher is the rest of the question
