The Kinetic theory can NOT be used to explain
allotropy
Brownian movement.
diffusion
Tyndal effect.
vaporization
Correct answer is A
No explanation has been provided for this answer.
The molar mass of a compound X is 56. its empirical formula is CH2. X is
butene
butyne
ethene
propene
propyne
Correct answer is A
\((CH_{2})x = 56\)
\((12 + 2)x = 56\)
\(14x = 56\)
\(x = \frac{56}{14}\)
\(x = 4\)
Hence, the empirical formula is \((CH_{2}) \times 4\)
= \(C_{4}H_{8}\)
