Answer:
It is in violation of the Heisenberg Uncertainty Principle. The Bohr Model considers electrons to have both a known radius and orbit, which is impossible according to Heisenberg. ... The Bohr Model does not account for the fact that accelerating electrons do not emit electromagnetic radiation
Answer:
Potassium chloride > Butanol >Propane > Ethane
Explanation:
Water is a polar solvent and it is likely to dissolve polar molecules.
KCl is ionic in nature and is completely polar and the solubility of the salt, potassium chloride is the highest.
Butanol can form hydrogen bonding with the water despite having a carbon chain. Thus, butanol will be at second.
Taking about, ethane and propane, both are non polar and least likely to dissolve in water. But, the extent of the London forces increases with the increase in the molecular weight. So, propane will dissolve faster than ethane.
The order is:
Potassium chloride > Butanol >Propane > Ethane
Answer:
the answer would be a i did the test
Explanation:
Answer:
the unknown substance is a protein
Explanation:
The biuret test is one of the tests for proteins. It can be used to detect peptide linkages. The biuret test is carried out in an alkaline solution. A coordination complex is formed leading to the appearance of a violet color.
Summarily, the biuret method is a colorimetric technique used to test for proteins and peptides. It involves the formation of a purple (violet) complex of Copper salts in alkaline solution.
Hence when the biuret reagent is added to an unknown substance and it turns purple, the unknown substance is a protein
Answer: Yes! you're all good. Alkali metals in group 1 are the most metallic :)
