Answer:
So ²³⁵UF₆ effuses 1.0043 times faster than ²³⁸UF₆
Explanation:
The rate of effusion of two gases A and B can be expressed by <em>Graham's law</em>:

Where M is the molar mass, and in this case A is ²³⁵UF₆ while B is ²³⁸UF₆.
So now we <u>calculate the molar mass of each mass</u>:
²³⁵UF₆ ⇒235 + 6*19 = 349 g/mol
²³⁸UF₆ ⇒238 + 6*19 = 352 g/mol
Putting the data in Graham's law:
= 1.0043
So ²³⁵UF₆ effuses 1.0043 times faster than ²³⁸UF₆.
Alkenes undergo
Electrophillic Addition Reactions. Electrophiles are added across double bond. In given reaction the
H⁺ is first added across double bond as the double bond being denser in electron density act as a neucleophile. A
carbocation formed depends upon the nature of Alkene, if alkene is
symmetrical (as in our case) then positive charge can get any position, but in case of
unsymmetrical alkene the positive charge will go to that carbon which is attached to more carbon atoms. Then the water molecule attacks the carbocation and forms
alcohol.
