a or c becuse it means you should answer it very wiseley
Answer:
Hello
you're answer should be E.HOCH2CH2OH
hope this answer is correct
An endothermic chemical reactions products tend to have a higher potential energy than the reactants. Thus making the /\ H positive, not negative.
Answer:
Electric Current
This is a flow of electrons (such as the flow of electrons in a wire to light up a lamp).
Insulator
These stop the electricity from flowing (think rubber and glass).
Resistance
This is slowing the flow of electrons (the current) and where some of the electrons' energy gets converted into heat.
Conductor
These allow electricity to flow easily through them (think copper and aluminum).
