Physical change is described as the change that affects the form of a chemical compound but not its chemical composition. It involves the change in physical properties.
When a solid is dissolved in the liquid the solid gets dissolved in the liquid there is no breakage in the bonds and same composition of the compounds are at the end of the change. When a solution changes colour due to the addition of an other substance the bonds are broken or formed between molecules or atoms. The substance with a certain set of properties is turned into different substance with different properties. Hence it is a chemical change.
Two liquids producing heat when mixed together results in the temperature change. The heat is produced due to the increase in the temperature. Hence it is a chemical change.
When two solutions are combined gas is released due to the temperature change. This is also a chemical change
Therefore the answer is A.
Answer:
Nitrogen is inert because its p-subshell is half-filled due to it has maximum exchange energy. Thus it is exists in stable form as like inert gas and it form triple bond (N≡N). N2 molecules is very stable and its dissociation energy is 225kcal/mol.
