Geometric isomerism
Positional isomerism
Structural isomerism
Optical isomerism
Correct answer is D
Optical isomers are molecules that are non-superimposable mirror images of each other and they are not identical. Molecules with a chiral carbon show this kind of isomerism. Chiral carbon, also known as asymmetric carbon, refers to carbon atom that are bonded to four different atoms or groups of atoms.
In the equation above, Y is
10H+ (aq)
5H+ (aq)
8H+ (aq)
4H+ (aq)
Correct answer is C

A reversible reaction
A spontenous reaction
An endothermic reaction
An exothermic reaction
Correct answer is D
In salts for which the hydration energy is higher than the lattice energy, solvation occurs with a release of energy in the form of heat. A reaction in which there is a release of energy as LIGHT OR HEAT is EXOTHERMIC.
