1 answer:

6 0

The nucleus is the positively charged core of an atom, which is surrounded by a cloud of negatively charged electrons. Nucleons are particles that the core of an atom consists of, namely positively charged protons and neutral neutrons. That is, thenucleus is made up of nucleons.

Photochemical chlorination of 1,2-dibromoethane gives a mixture of two stereoisomers of C2H3Br2Cl. Write their structural formul

Sever21 [200]

Answer:

Enantiomers

Chiral

Yes they will be formed in equal amount.

Explanation:

The Two possible stereo isomers are formed due to generation a chiral center in the molecule.

There will be a carbon with all the four groups different.

The two isomers will be called as enantiomers, which are non super-imposable mirror image of each other.

They are named as "R" or "S'" based on the selection rule.

The IUPAC names are also given in the figure.

The two isomers will be formed in equal amount as during photochemical chloriantion of a compound free radicals are generated (which are trigonal planar) and the other radical may attack from either side (front side or back side) giving the two stereo-isomers.

What kind of bond is formed between hydrogen and chlorine atoms?

SVETLANKA909090 [29]

Answer:

The answer to your question is Covalent

Explanation:

Both, Hydrogen and Chlorine are non metals, when two nonmetals attach the share electrons and the type of bonding formed is polar covalent because they have different sizes, hydrogen is smaller than chlorine.

How many cubic feet of air at standard conditions 1.00 atm are required to inflate a bicycle tote of .50 cu. Ft. To a pressure o

Alexeev081 [22]

As I am reading the problem, I see they gave you two pressures, one volume and they are asking for another volume. this should give you a hint that you need to use the following formula.

P1V1= P2V2

P1= 1.00 atm
V1= 0.50 ft³
P2= 3.00 atm
V2= ?

Now we plug the values

(1.00 x 0.50)= (3.00 x V2)

V2= 0.17 ft³

Decribe an example of how external temperature may affect human body functions

marusya05 [52]

If your body temperature falls to 95°F (35°C) or lower, you have “hypothermia.” This condition can potentially lead to cardiac arrest, brain damage, or even death. If your body temperature rises as high as 107.6°F (42 °C), you can suffer brain damage or even death.
