Answer:
They are resonance contributors
Explanation:
Resonance structures are structures that differ only in the distribution or placement of electrons.
Considering the two structures, we can easily see that the two species have the same total number of bonds and electrons differing only in the distribution of these electrons.
Hence, they are resonance contributors.
It must be made of matter because anything and everything is made up of atoms. The other three options are made of atoms but they are also matter.
Volume of tank =
(given)
Since,
So,

For
:

The significant rule for multiplication, states that the number of significant figures in the answer obtained by multiplication is determined by the value with the lowest number of significant digits.
Since, the minimum number of decimal places in the above multiplication operation is 1 so, the final result must be upto 1 decimal place only.

Hence, volume in
is 243.5.
So..... I believe this is a Convergent boundary and mountains..
Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds
