Answer:
number of energy levels
Explanation:
for example hydrogen and helium are in period 1 and they have 1 energy level
<span>To compare the energy of microwaves, IR-B, and IR-A, we need to compare how long the wavelengths are for each wave. Through the intervals given, we can determine that we in order from greatest to least energy, the order is IR-A, IR-B, microwaves.</span>
The triple bonds are the shortest bonds. So the correct option is C.
<h3>What are bonds?</h3>
Chemical bonds are the bonds that are the attraction between ions or molecules that makes up compounds. There are different types of bonds They are covalent, ionic, hydrogen, electrostatic, etc.
A single bond is formed when only one electron is shared between atoms. As the same triple bonds are formed when there are three electrons shared between atoms. Triple bonds are the shortest because they have less strength.
Thus, the correct option is C. triple bonds are the shortest.

Answer:
The answer to your question is A. Decomposition
Explanation:
In the picture, we can observe that there is only one reactant that after the reaction are formed two products.
We observe that this is a decomposition reaction.
It is not a synthesis reaction, this reaction is the opposite of a decomposition reaction.
In a single-replacement and double-replacement reaction, there is an interchange of cations between the reactants, this does not happen in the picture.
0.2 m/s! keep in mind, speed= distance divided by time :D
