Acetonitrile + C2H5MgI = A + HoH = B Here B is1) Acetone, 2) Acetaldehyde, 3) But-2But-2-one, 4) Butanal

Evaporation – The phenomenon of change of liquid vapours at any vapours at any temperature below it’s boiling point is called evaluation. Factors affecting evaporation – 1) Wind energy – When the wind energy is increase then the rate of evaporation is also increase. (Wind energy rate of evaporation ) 2) Temperature – When the…

Evaporation – The phenomenon of change of liquid vapours at any vapours at any temperature below it’s boiling points it is called evaluation. Factors affecting evaporation: 1) Wind energy – when the Wind energy is increase the rate of evaluation is also increase. 2) Surface area- when the surface area is increase then the rate…

A sample of an ideal gas expands reversibly and isothermally at 300 K from a volume of 2 L to 10 L. The number of moles of the gas is 1 mole. Calculate the work done by the gas during the expansion. Use the formula for reversible isothermal expansion: w = -nRT lnleft(frac{V_2}{V_1}right) Given: =…
