Answer:
electron shells
Explanation:
Eletrons are on the outeermost part of the atom called electron shells.
Answer:
a) The heat which we supply to water during boiling is used to overcome these forces of attraction between the particles so that they become totally free and change into a gas. This latent heat does not increase the kinetic energy of water particles and hence no rise in temperature takes place during the boiling of water.
b) Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.

The most difficult concept will be the concept of patient drug tolerance because there are many drugs that have different side effects for different patients. Therefore, it is necessary to understand the response of certain drugs to different patients. This will help avoid wrong drug combinations. This can cause side effects.
To learn more about this concept, you need to do your homework on these different drugs and the tolerance reactions you may experience, and attend some drug tolerance seminars, where the speaker will give you more ideas . And a further explanation of the concept.
Another topic in chemistry that is most tough to understand is moles. We can understand this concept by understanding the fact mole is an amount of a substance which may be atoms, molecules, ions, etc which have exactly 6.02214076 * 1023 'elementary entities' of the substance.

The product formed when benzene reacts with isobutyl chloride in the presence of AlCl3 is tertiary butyl benzene.
THE CHEMICAL REACTION AS
step 1 : CH₃ - CH - CH₂Cl + AlCl₃ → CH₃ - CH₂ -CH₂ - CH₂⁺ + AlCl⁻
step 2: CH₃ - CH₂ - CH₂ - CH₂⁺ ---H SHIFT--→ (CH₃)₃C⁺
PRODUCT
C₆H₆ + (CH₃)₃ C⁺ → C₆H₆ ( CH₃)₃ C⁺
Hence the product formed is tertiary butyl benzene.
