Dolphins use a method called echolocation to detect things such as obstacles and prey in the water. If a dolphin swimming in seawater at 25°C sends a 220-dB click with a frequency of 120.0 Hz, and then detects the reflection of the click exactly one-twentieth of a second later, approximately how far away is the object?

When molecules have the same number of each element but those atoms are arranged differently they are known as____________.
Karo-lina-s [1.5K]

Answer: Structural Isomers

Explanation:

The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.  

Isomers are of two types: structural isomers and stereo isomers.

Structural isomers are isomers in which molecules with the same molecular formula have different bonding patterns.

Stereoisomers are isomers in which molecules have the same molecular formula and sequence of bonded atoms but differ in the three-dimensional orientations of their atoms in space.

Thus when molecules have the same number of each element but those atoms are arranged differently they are known as Structural isomers.

22.4 L is the volume of any gas regardless of atmospheric conditions.<br><br> O True<br><br> O False
Contact [7]
This is false. One mole of a gas occupies 22.4 L at STP, which is taken to be 0°C (273 K) and 1 atm. If atmospheric conditions depart from these values, this assumption cannot be used.
