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.
(Please kindly find the attached document containing the lewis structure)
<u>Answer:</u> The standard potential of the cell is 0.77 V
<u>Explanation:</u>
We know that:
The substance having highest positive reduction potential will always get reduced and will undergo reduction reaction.
The half reaction follows:
<u>Oxidation half reaction:</u>
<u>Reduction half reaction:</u> ( × 2)
To calculate the of the reaction, we use the equation:
Substance getting oxidized always act as anode and the one getting reduced always act as cathode.
Putting values in above equation follows:
Hence, the standard potential of the cell is 0.77 V
B and C because:
- mercury is a metal so it will appear silver
- mercury will be in most old thermometers, which are made from glass
Answer:Lava is molten rock on the surface of the Earth. Name the two smallest particles of pyroclastic material. Dust is the smallest of the pyroclasts and ash is the second smallest.
Explanation:
Answer:
a.One or more electrons will move to a higher energy orbit
Explanation:
Absorbing energy means that the electron gets excited and jumps to a higher level.
