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
The systematic name for the coordination compound [Cr(H2O)4Cl2]ClO3 is tetraaquadichlorochromium(III) chlorate.
The coordination compound you want to name falls under the subject of Chemistry, specifically inorganic Chemistry. The compound is [Cr(H2O)4Cl2]ClO3. The systematic name for this compounds is tetraaquadichlorochromium(III) chlorate. This nomenclature follows rules set out by Alfred Werner where the metal is specified (chromium), the number and type of ligands or ions the metal is bonded to are defined (tetraaqua, which indicates four water molecules, and dichloro for two chlorine ligands), and the oxidation state of the metal is given (III). Finally, the counter ion is named (chlorate).

Answer:
Explanation:
Aqueous solution of copper sulphate
is acidic in nature, as when copper sulphate on dissolving with water, following chemical reaction takes place :
CuSO4 + 2 H2O ====> Cu(OH)2 + H2 SO4
As we can see, copper hydroxide and sulphuric acid is generated in this chemical reaction.Copper hydroxide is a weak base whereas sulphuric acid is a very strong acid which results into increase in acidity of the solution.
Thus, the aqueous solution of copper sulphate is acidic in nature.
It states the fact, which we now know, that electrons are responsible for the chemical bonding. According to this theory, valency is the number of electrons present in the outermost energy shell of the atom. This energy shell is called valency shell.
The electrons located in the valence shell of an atom are responsible for forming chemical bonds by sharing, donating or accepting electrons.
The parts of the atom responsible for chemical bonding are the electrons, which are located in the outermost shell of the atom, also known as the valence shell. These electrons can be shared, donated, or accepted to form chemical bonds with other atoms. For example, in a covalent bond, electrons are shared between atoms. In contrast, in an ionic bond, electrons are transferred from one atom to another, creating ions that are attracted to each other and form a bond.

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.
