Hydrogen phosphate of certain metal has a formula MHPO_4 , the formula of metal chloride is
(A) Hydrogen atom consists of only one electron but its emission spectrum has many lines. (R) Only Lyman series is found in the absorption spectrum of hydrogen atom whereas in the emission spectrum, all the series are found.
Given samples of 1cm^(3) of Hydrogen and 1cm^(3) of Oxygen both at N.T.P., which sample has larger number of molecules
The number of molecules of hydrogen in 1 cc of hydrogen gas at NTP.
Ionisation potential of hydrogen is ?
A sample of oxygen at NTP has volume V and a sample of hydrogen at NTP has the volume 4V. Both the gases are mixed. If the speed of sound in hydrogen at NTP is 1270 m/s, that in mixture is
