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
Inorganic chemistry studies the chemical compounds in inorganic, or non-living things such as minerals and metals.
Answer: 
Explanation:
Molarity is defined as the number of moles dissolved per liter of the solution.
Normality is defined as the number of gram equivalents dissolved per liter of the solution.
Thus 
In an ionic compound the atoms are linked via ionic bonds. These are formed by the transfer of electrons from one atom to the other. The atom that loses electrons gains a positive charge whereas the atom that accepts electrons gains a negative. This happens in accordance with the octet rule wherein each atom is surrounded by 8 electrons
In the given example:
The valence electron configuration of Iodine (I) = 5s²5p⁵
It needs only one electron to complete its octet.
In the given options:
K = 4s¹
C = 2s²2p²
Cl = 3s²3p⁵
P = 3s²3p³
Thus K can donate its valence electron to Iodine. As a result K, will gain a stable noble gas configuration of argon while iodine would gain an octet. This would also balance the charges as K⁺I⁻ creating a neutral molecule.
Ans: Potassium (K)
