Match items of column I and II
| Column I (Mixture of compounds) | Column II (Separation Technique) | ||
| A | H2O/CH2Cl2 | i | Crystallization |
| B | ![]() | ii | Differential solvent extraction |
| C | Kerosene/Naphthalene | iii | Column chromatography |
| D | C6H12O6/NaCl | iv | Fractional Distillation |
A. H2O/CH2Cl2→ ii, CH2Cl2>H2O (density) so they can be separated by differential solvent extraction.

C. Kerosene / Naphthalene → iv. Fractional distillation.
Due to different B.P. of kerosene and Naphthalene it can be separated by fractional distillation.
D. C6H12O6/NaCl→ i. Crystallization.
NaCl (ionic compound) can be crystallized.
Given below are two statements:
Statement I: D-(+)-glucose + D-(+)-fructose $\xrightarrow{H_2O}$ sucrose sucrose $\xrightarrow{\text{Hydrolysis}}$ D-(+)-glucose + D-(+)-fructose
Statement II: Invert sugar is formed during sucrose hydrolysis.
In the light of the above statements, choose the correct answer from the options given below -
Two circular discs of radius \(10\) cm each are joined at their centres by a rod, as shown in the figure. The length of the rod is \(30\) cm and its mass is \(600\) g. The mass of each disc is also \(600\) g. If the applied torque between the two discs is \(43\times10^{-7}\) dyne·cm, then the angular acceleration of the system about the given axis \(AB\) is ________ rad s\(^{-2}\).

Match the LIST-I with LIST-II for an isothermal process of an ideal gas system. 
Choose the correct answer from the options given below:
Which one of the following graphs accurately represents the plot of partial pressure of CS₂ vs its mole fraction in a mixture of acetone and CS₂ at constant temperature?

The scientific study of matter’s properties and behaviour is known as chemistry. It is a natural science that studies the elements that makeup matter, as well as the compounds, made up of atoms, molecules, and ions: their composition, structure, qualities, and behaviour, as well as the changes that occur when they mix with other things.
