Answer:
b living and non living things. If we look at the question the ocean is non living but the forest and grassy meadow are examples of living things
Atomic number is the number of protons in an atom. Since these are all Hydrogen, the number of protons remains the same, and the Atomic Number for each is 1. Mass number is the number of Protons and Neutrons in an atom. So, Protium is 1, Deuterium is 2, Tritium is 3. The number of neutrons is stated in the question (Protium 0, Deuterium 1, Tritium 2). Hope this helps, if you wouldn’t mind marking brandies if it did!
The answer is gas
I hope I help
Explanation:
We have,
The most probable speed of an oxygen molecule in the gas phase at room temperature is 450 m/s.
The formula of the most probable speed of a gas molecule is given by :
So,
The RMS speed of the gas molecule is given by :
Use equation (1) in above equation :
It is clear that the RMS speed of the gas molecule is greater than 450 m/s.
