1) As can be seen from any 1H NMR chemical shift ppm tables, hydrogens which have δ values from 2ppm to 2.3ppm are hydrogens from carbon which is bonded to a carbonyl group. From this, we can conclude that our hydrogens belong to the type, but from 2 different alkyl groups because of 2 different signals.
2) So, one alkyl group is CH3 and second one can be CH or CH2.
3) If we know that ratio between two types of hydrogens is 3:2, it can be concluded that second alkyl group is CH2.
4) Finally, we don't have any other signals and it indicates that part of the compound which continues on CH2 is exactly the same as the first part.
The ratio remains the same, 3:2 ie 6:4
Answer:
The reaction that takes place in an electro-chemical cell is the Redox reaction, a type of reversible reaction combining both oxidation and reduction reactions.

Answer:
Explanation:
Take out your periodic table.
The choices that have one 1 member of the periodic table on it are elements.
He is the symbol for Helium
O2 oxygen
C3 but this is really odd. It is Carbon but Carbon usually does not combine in 3s.
The rest are all compounds (they are made up of the elements on the periodic table). For example
H2SO4
is made up of 2 Hydrogens
1 sulfur
4 oxygens.
All the others do exactly the same thing.
