Wavelength= velocity/frequency
wavelength= (3.0 x 10^8m/s) / 7.5 x 10^12 Hz)
you can do the math
I am assuming u that 108 is 10^8 and the 1012 is 10^12
Alkali metal - Group 1 metal
Alkaline earth metal - Group 2 metal
Iron triad - metal
Halogens - most are diatomic and are nonmetals - Cl2, Br2, I2
Noble gases - nonmetals and are not reactive due to full valence shell.
Boron group - metalloid
Oxygen group - oxygen molecule - a diatomic molecule composed of oxygen atoms, which are nonmetals.
Carbon dioxide gas is dissolved in carbonated soda.
Mercury,
Hope I helped :)
Answer:
Explanation:
From the given information :
The molecular mass m/z of chlorobenzene = 112
Also the isotope of chlorine are:
SInce isotopes are atoms with the same atomic number but different mass number .
With an abundance of 3:1
FOr a molecular ion peak; there is need for the presence of
:;
As such the m/z value of M⁺ = 112 for a molecular ion peak
The approximate abundance at 112 for a molecular ion peak will be:
abundance of 15% × 3
= 15% × 3
= 45%
