Increase because friction would decrease.
Coating the ramp with a smoother surface will decrease the friction. A decrease in friction will help to slide any object up the ramp easily. Thus, a lesser energy will be spent as compare to earlier. Hence, the ramp's efficiency will increase.
Answer:Chemical energy
Explanation:, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.
Answer:
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Explanation:
The elements found in the Group 1, or the Alkali Metal Group, have electronic configurations that end in
.This means that they have 1 electron readily available to release in order to achieve a stable state.
When these atoms release the valence electron, they will achieve a stable state. For example, Lithium's stable state will be
and Sodium will be
.
The oxidation state will then be +1.
The answer is C.
