Certain fish species use bioluminescence as a form of "night light". Some use it for communication. Certain species of crustaceans send out coded signals to others of their own kind during mating season. Other creatures use bioluminescence as a trap.
The Pcl6 has 48 bonded electrons and 18 lone pairs.
The Lewis structure of Pcl6 is as follows: -
Phosphorous is bonded with 6 chlorine atoms with 18 lone pairs.
Lewis structures, also known as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDS), are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. [1][2][3] A Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds.
In Lewis structure, atoms are bonded with single bonds. If total number of electrons are 't' and number of bonds are 'n', then t-2n number of electrons are to be placed. Once the central atom is placed, they need to complete the octet rule.

Answer:
Explanation:
Hello there!
In this case, since the heat of fusion is a property that allows us to calculate the heat involved during the change from solid to liquid (fusion) and is calculated as shown below:
In such a way, given the heat involved during this process and the mass of copper, we calculate the heat of fusion as shown below:
Or in kJ/mol:

Answer:
The footprints of a dinosaur and the burrow of an ancient shrimp are examples of - Trace Fossils
Explanation:
A trace fossil or ichnofossil is defined as a geological record of biological activity. These provide us with indirect evidence of life in the past, such as the footprints, burrows, tracks, borings, etc that are left behind by animals, rather than the preserved remains of the body of the actual animal itself.
Answer:
induced-dipole induced dipole forces.
