The best way to determine the presence of halogens is by adding a silver nitrate solution to the solvent. This is because all halogens, except for fluorine, produce a precipitate with silver nitrate solution.
Chlorine produces a white precipitate, bromine produces a pale cream colored precipitate and iodine produces a yellow colored precipitate.
If further testing is required, concentrated sulfuric acid may be added. The sulfuric acid will produce misty fumes with fluorine and chlorine, brown fumes with bromine and purple fumes with iodine.
Answer:
Its kinetic energy
Explanation:The dart is in motion because of the potential energy being stored and turned into kinetic energy, plus since the dart is aerodynamic, it would have more speed for it to hit the dart board.
...."heavier". *The definition of radioactive decay shall do its explanation.
Answer:
See explanation
Explanation:
We know that in the presence of strong oxidizing agents such as permanganate , aldehydes are oxidized. This oxidation is often accompanied by a colour change.
The colour change in the permanganate oxidation of benzaldehyde is caused by the inorganic permangate. The colour changes from purple to colourless because Mn^7+ is reduced to Mn^2+.
The benzaldehyde is readily oxidized to benzoic acid in the presence of permanganate.
According to the research, the correct option is Atoms can join together to form a new substance. It is the statement that correctly describes atoms.
<h3>What are atoms?</h3>
It refers to the smallest amount of a chemical element that has its own existence and is considered indivisible.
Atoms have the properties of the chemical element they compose and, in turn, can combine with each other to form chemical bonds, and to constitute different chemical compounds and substances that make up the organs and organ systems in living beings, the materials generated in industry, and all the matter that makes up the universe.
Therefore, we can conclude that according to the research, the correct option is Atoms can join together to form a new substance. It is the statement that correctly describes atoms.
