°°The next Lunar Eclipse is on March 23, a Wednesday THIS YEAR - 65 days left!
°° A Lunar Eclipse happens when the moon passes directly behind the earth into its umbra, or, shadow. This can occur only when the sun, Earth and moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a Lunar Eclipse can occur only the night of a full moon. The type and length of an eclipse depends upon the Moon's location relative to its orbital nodes. Isn't that cool?

b. cannot be broken down further.
c. are all composed of carbon.
d. have no mass.
Answer:
B
Explanation:
Atoms are those particles which cannot be broken down further. But, later on the subatomic particles were discovered
John Dalton's Atomic Theory states that atoms are indivisible and cannot be broken down further. They combine to form molecules and are not all composed of carbon. Atoms do have mass.
John Dalton, an English chemist, is famous for his theory of atomic structure, also known as Dalton's Atomic Theory. According to this theory, atoms are the tiniest particles of matter which cannot be divided or broken down further into simpler substances by chemical means. Thus, the correct answer to the question would be (b) - atoms cannot be broken down further.
Atoms can combine in various proportions to form molecules, but they themselves do not contain molecules. Also, not all atoms are composed of carbon, there are many other elements such as hydrogen, oxygen, nitrogen, to name a few. Finally, atoms do possess mass, it is one of their fundamental properties.

B The oxygen in the air forms ozone in presence of UV rays
C Dust and soot particles being suspended in the air
D Sulphur dioxide being released in the air
the answer is B not A
let me explain why see a says water vapor in the air turns to liquid water in the form of rain see that is a physical change not a chemical change it is B because it is undergoing a chemical change by the uv rays for that reason it is not D because that is just releasing sulfur dioxide in the air that is not a chemical change nor a physical change so then i leaves us with C so C is wrong because it just being suspended in the air not physical or chemical change
can i also have brainlyest i never had it before
