Proteins are organic molecules composed of Carbon, Hydrogen, Oxygen and Nitrogen.
Answer:
Explanation:
The reaction can be represented by this nuclear equation: 23892U → 23490Th + 42He + Energy.
Answer:
( a ) soluble
( b ) soluble
( c ) insoluble
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. ,<u> if a compound is polar then it will dissolve in a polar compound only , </u>and
<u>if a compound is non - polar then it will dissolve in a non - polar compound only .</u>
Hence , from the question ,
( a )
Methanol and water as we know are both polar species , hence , according to the principle - soluble .
( b )
Hexane and cyclohexane
Both the species are polar species , hence , according to the principle - soluble .
( c )
Hexane and water
In this case ,
Hexane , is non polar and water is polar , hence , the mixture will be non soluble .
Answer:
D
Explanation:
According to the law of conservation of mass, matter can neither be created nor destroyed. The implication of this is that the total mass of reactants should be equal to the total mass of products.
There should be equal masses of reactants and products on both sides of the reaction equation. This most important condition is only satisfied by option D.
