Redox reactions consist of reduction and oxidation reactions
oxidation reactions are the giving out of electrons, the oxidation number of the species giving out the electrons increases during oxidation
reduction reactions are taking in electrons and the oxidation number of the species taking in electrons reduces after reduction
in the reaction Ca + Cl₂ --> CaCl₂
oxidation numbers of Ca in Ca - 0 and CaCl₂ - +2
oxidation numbers of Cl in Cl₂ - 0 and CaCl₂ - -1
oxidation number of Ca has increased from 0 to +2 therefore Ca is oxidised
Answer:
A. Vegetable oil
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. , if a compound is polar then it will dissolve in a polar compound only , and
if a compound is non - polar then it will dissolve in a non - polar compound only .
Hence , from the question ,
A. Vegetable oil is a non polar compound ,
B. Polar compound
C. ionic compound , is a polar compound .
Since , wate is polar in nature , hence it will get dissolved in a only polar compound ,
Therefore ,
Water will not get dissolved in vegetable oil , being it a non - polar compound .
Answer:
The nucleus is like the mayor's office because it controls what happens in the cell. The mitochondria is the powerhouse of the cell because it gives the rest of the cell energy to perform the tasks they need to do.
Explanation:
Answer:
Red dye
Explanation:
In the given question, the complete question has not been provided but the propanone is used as a solvent in paper chromatography. The paper chromatography was performed for the black ink in which the black ink got separated in the red, blue and yellow colour.
From these three colours that are red, blue and yellow, the dye which is most soluble in propanone was red as red colour moved the most in the given chromatogram and the dye which travelled the most is most soluble in propanone.
Thus, red dye is the correct answer.
Answer:
there should be around 41 moles
