(5.50) ( 6.02 *10^23)
Explanation:
The number of molecules equals the number of moles times Avagadro's number.
Answer:
substitution ,elimination,addition organic reactions
Explanation:
In a substitution reaction, one atom or a group of atoms is substituted by another atom or a group of atoms to form a new substance.Elimination reaction
There are some reactions which involve the elimination or removal of the adjacent atoms. After these multiple bonds are formed and there is a release of small molecules as products.
One of the examples of elimination reaction is the conversion of ethyl chloride to ethylene.
Addition reaction is nothing but just the opposite of elimination reaction. In an addition reaction, the components A and B are added to the carbon-carbon multiple bonds and this is called addition reaction. In the reaction given below when HCl is added to ethylene, it will give us ethylene chloride.
HCl + CH2=CH2→ CH3CH2Cl
(4) total number of valence electrons, because they exist in the same group.
Answer:
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
