Answer:
Answer: The kinetic energy decreases as potential energy increases. I am pretty positive because of the definition of these two. Hope this helps!
Explanation:
Answer:
it depends on the material of the bowl. if the material is a good heat conductor, then it is a bad insulator vice versa.
The valence electrons are in the s-orbital.
Increase the Surface Area of the Reactants. Increasing the surface area of the reactants increases the rate of the reaction. More surface area means more collisions of the reactant molecules and an increased rate of the reaction. This occurs when reactants are made to react in powdered form
Answer:
B. Electrons are gained, so the oxidation number decreases.
Explanation:
Reduction is the <em>gain of electrons</em>.
Oxidation number is the charge that an atom <em>appears</em> to have when we count its electrons in a specific way.
Electrons have a negative charge so, if an atom gains electrons, its charge (oxidation number) becomes more negative. The oxidation number decreases.
If electrons are given off, the atom is being oxidized. Loss of electrons is <em>oxidation</em>.
