Penguins have webbed feet to help them swim, waterproof feathers and very good vision underwater , they also have thick skin and blubber to help them keep nice and warm so they can have fun and fish for food with out worrying about being very cold. Hope that helped UwU
Answer : The one mole atom of carbon is not equal to 1 mole of substance.
Explanation :
As we know that,
number of hydrogen molecules present in 1 mole of substance.
and,
At STP, 22.4 L volume of hydrogen gas present in 1 mole of substance
and,
number of sodium molecules present in 1 mole of substance.
and,
number of gold molecules present in 1 mole of substance.
All these options are equal to the 1 mole of substance.
While the option, one mole atom of carbon is not equal to the 1 mole of substance because 1 mole of atom of carbon is equal to 12 grams.
Hence, the one mole atom of carbon is not equal to 1 mole of substance.
Answer:
Explanation:
From the 1 g sample you have:
0.546 grams of cobalt chloride
1-0.546=0.454 grams of water
Now:
1) The salt
Of the 0.546 g, 0.248 g are cobalt (Mr=58.9) and the rest id Cl (Mr=35.45):
Dividing:
So the molecular formula will be:
2) The water
The water's molecular weight is M=18 :
Bonding with the Co:
The complete formula of the hydrate:
42- 8 = 34 sand dunes must be the answer
hope so it helps
Quantum is deemed to be a distinct container with energy kept in, whereas photon is considered as an elementary particle. Photon and quantum are two very significant principles talked about in modern physics. These principles are broadly used in quantum chemistry, quantum physics, electromagnetic theory, particle physics, optics, etc. These principles are also applied in a lot of actual world applications such as high resolution microscopy, LASERs, measurements of molecular distances, photochemistry, and quantum cryptography. It is highly important to have knowledge and a good understanding in photon and quantum so that we could excel in the aforesaid fields. A photon is an elementary particle, however, a quantum is not an elementary particle. A quantum does not have the properties of both wave like and particle like, but a photon does. A photon is not about a measure of quantity and can be defined as a quantum of energy, on the contrary, a quantum can be described as a measure of quantity.
