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 .
Speed of light = 3x10^8 m/s
Mass of electron = 9.11x10^-31 kg
70% of 3x10^8 = 2.1x10^8 m/s
206.8*9.11x10^-31 = 1.88x10^-28 kg
Equation for wavelength is: wavelength= plancks constant / (mass*velocity)
Plancks constant = 6.62x10^-34 m^2 kg/s
Plug all of these in and you get: 6.62x10^-34 / (1.88x10^-28/2.1x10^8) = 739.47
Your answer is 739.47 m
The representation that would best explain the properties of the gas fluorine would be a <span>electron dot structure. From this structure, you can see how many electrons are available for bonding since the electrons are the ones responsible for interacting with other atoms. </span>
Answer:
H-O
Explanation:
because oxygen and hydrogen have very high difference in electronegativity
