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.

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.

0.056dm3
0.224dm3
224.000dm3
56.000dm3
Correct answer is A
Q = 193 x 5 = 965C
40H \(\mapsto\) 2H2O + O2 + 4e
4 x 96500C = 22.4dm3
965C = x
x = \(\frac{22.4 \times 965}{4 \times 96500}\)
= 0.056dm3
