here we have to explain the development of the atomic theory by the atomic emission spectrum.
The most important aid in determining the structure of an atom has been study of radiation emitted and absorbed by the elements. The glowing atoms of an element emit radiations.
These are called the atomic spectra. This study helped to understand the structure of the atoms.
To explain the atomic spectra the Bohr's model was introduced. The postulates of the Bohr's model explain the fine spectrum of the atom up to the particle nature of the electrons.
Later some modification on the Bohr's postulates was made to explain the wave nature of the electrons as well. But the atomic spectra is best be understood by the Bohr's atomic model which developed the atomic theory.
Thus the understanding of emission spectrum of atom to develop the atomic theory is explained.
Answer:
A
Explanation:
PV=nRT
PV/nT
V/T -> (1)/(300)=(x)/(150)
x=.420
Answer:
The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.
Explanation:
The degree of unsaturation is calculated through the following formula:
2n + 2 - H / 2
n = Total number of hydrogen in given compound
There are six hydrogen in given compound, now we will calculate the degree of unsaturation by putting the value of n= 6
(2(6) + 2 - 6 )/ 2
(12+ 2 - 6) / 2
(14 - 6) /2
8 / 2 = 4
The degree of unsaturation for a compound with molecular formula C₆H₆ is 4.
The given compound is benzene and degree of unsaturation is 4. Three double bond and one ring.
1 mole of any gas under STP has volume =22.4 L
4.76 mol*22.4 L/1 mol ≈ 107 L
Answer: the charge on each electron
