Copper oxide is the only product, and it contains copper and oxygen.
one of the reactants is copper, so the other reactant must be oxygen.
The copper metal must have combined with something in the air.
Answer:
C) The most efficient fusion reactors would use heavier forms of hydrogen.
Explanation:
From the information presented to us in the question, the third sentence reveals that heavier forms of hydrogen produces larger amount of energy and most importantly reacts more efficiently when fusion occurs.
<em>In fact, the </em><u><em>heavy isotopes of hydrogen—deuterium and tritium—react more efficiently</em></u><em> with each other, and, when they do undergo fusion, they yield more energy per reaction than do two hydrogen nuclei. </em>
The answer is Kw = [H20⁺][⁻OH]. The expression for kw, the ion–product constant for water is Kw = [H20⁺][⁻OH].
