Work is measured in joules. hope this helps!
sun light and chemical create photochemical smog
Answer:
<u>The half-reaction that occurs on the anode of an electrolytic cell is called oxidation.
</u>
This can easily be depicted by a chemical reaction as such <u>"Zn(s) = Zn2+ (aq) + (2e-)"
</u>
While, the Zinc in this reaction loses two elections. Hence copper gains those electrons and becomes solid.
<em>These reactions occurring on the anode are called positive reactions.
</em>
While the reaction that occurs on the cathode is called reduction. This reaction can be represented by this equation "<u>Cu2+ (aq) + 2e- = Cu(s)</u>".
<u>These non-spontaneous reactions occurring in an electrolytic cell together are called redox reactions. These generate electrical energy.</u>
Answer:
The valence electrons are the only parts of an atom that make chemical bonds. Noble gases don't form chemical bonds because they have a full outer shell (8 electrons).
