Answer:
Reductio is gain of electrons, while oxdation is loss. The oxidtion states of carbon in the reaction will show either of oxidation or reduction occurrence.
→ 
Explanation:
Electrons displacement is explained for each reaction below:
- +2 to +4 = loss of 2 more lectrons-------oxidation
- +4 throughout reaction----no exchange of electrons
- -4 to +4 = loss of 4 electrons-----oxidation
- 0 to -2 = gain of 2 electrons-----reduction
Answer:
Adduct, donate, accept
Explanation:
Lewis acids are those having suitable vacant orbital for electron acceptance and forming a covalent bond with an electron rich species. Example: 
(B has vacant 2p orbital for electron acceptance)
Lewis bases are those having energetically available unshared electrons that can be donated to an electron deficient species and form a covalent bond. Example: 
(N has energetically available lone pair)
So, product of Lewis acid-base reaction is an adduct (
) where a new covalent bond is formed between B and N.
Answer:
It can be formed either through a process of evaporation or sublimation. Unlike clouds, fog, or mist which are simply suspended particles of liquid water in the air, water vapour itself cannot be seen because it is in gaseous form

Answer:
Option E
Explanation:
As work is dot product of force and displacement
W=FdCos0
As Cos 0=1 so W=F.d(1)
W=F.d
as Cos 90=0 so no work will be done when angle between force and displacement is 90 degree. At angle between force and displacement is 180 degree then negative value com as Cos 180= -1
The answer is true, particles in the gaseous state are the furthest apart
