Answer:
The possible isomers of C2H2Br2 are Cis- 1,2-dibromoethene, Trans-1,2-dibromoethene and 1,1- dibromethene
Explanation:
Isomerism is the phenomenon whereby organic molecules have the same molecular formular but different structure formular or spatial arrangement.
- When it has different structure formular, then it is referred to as Structural isomerism
- When it has different spatial arrangement, then it is referred to as Stereoisomerism
Dibromoethene has 2 Stereoisomer (Cis- 1,2-dibromoethene andTrans-1,2-dibromoethene ) and 1 structural isomer (1,1- dibromethene)
The lewis structures are structures showing the outer electron used in bonding.

The solution for this problem is:
C6H5NH3Cl is a strong salt: C6H5NH3+ + Cl- C6H5NH3+ + H2O <-----> C6H5NH2 + H3O+
K = Kw/ Kb= 1.0 x 10^-14 / 3.8 x 10^-10= 2.6 x 10^-5
=2.6 x 10^-5 = x^2 / 0.240-x
x = [H3O+] = 0.00251 M
pH = 2.60 is the concentration
Properties (especially chemical properties) of elements are usually determined by the valence shell electrons. Because silver and iron have a different number of valence shell electrons, their chemical properties are different.
I think the correct answer would be the third option. The reason I2 has a higher melting point than F2 is because I2 possesses a more polarizable electron cloud. I2 contains more electrons than F2 which would result to a stronger intermolecular forces. Having stronger intermoleculer forces would mean more energy is needed to break the bonds so a higher melting point would be observed.
