The mass is the number of n + p if you subtract p from mass you will find n
164 - 59 = 105
The bigger molecule has more interactions and hence the higher b.p. CH3CH2OCH2CH3 is a bigger molecule than CH4 and CH3CH3, so has more dispersion forces. It also has dipole-dipole forces due to the polarised C-O bonds. CH3OH and CH3CH2OH have hydrogen bonds due to the very electronegative O atom bonded to the H atom

<span>The star's main fuel during its lifetime is hydrogen. It is said that a star is composed of 97% hydrogen and 3% helium. Once the hydrogen of a star is gone, the star becomes old because it burns hydrogen during its lifetime.</span>
Answer:
94.74 km/hr
26.3 meters/sec
Explanation:
150 km/(95/60) hr = 9000/95 kph = 94.74 km/hr
(150 km * 1000m/km)/(95 min * 60 sec/min) = 150000/5700 m/sec
= 26.3 meters/sec
Hopefully, this is right!
Answer:
option B
Explanation:
An Object that has linear Kinetic energy so, it must be moving.
Expression of Kinetic energy
From the expression above we can clearly see that Kinetic energy is directly proportional to velocity of the object.
If the body has kinetic energy so, it must be moving with certain velocity.
Hence, the correct answer is option B
