Which of the following materials, used in construction, is an industrial waste product?
Show Hint
- Lime
- Fly Ash
- Sand
- Brick
The Correct Option is B
Solution and Explanation
Step 1: Identify which of the given materials is an industrial waste product.
- Lime: A naturally occurring material used in construction, but not a waste product.
- Sand: A naturally occurring granular material, not an industrial byproduct.
- Brick: Manufactured from clay and other materials but not classified as industrial waste.
- Fly Ash: A fine powder byproduct from coal combustion in thermal power plants, widely used in construction.
Step 2: Fly ash is utilized in the production of cement, concrete, and bricks due to its binding properties and environmental benefits.
Thus, the correct answer is option B Fly Ash.

- A linear octasaccharide (molar mass = 1024 g mol$^{-1}$) on complete hydrolysis produces three monosaccharides: ribose, 2-deoxyribose and glucose. The amount of 2-deoxyribose formed is 58.26 % (w/w) of the total amount of the monosaccharides produced in the hydrolyzed products. The number of ribose unit(s) present in one molecule of octasaccharide is _____.
Use: Molar mass (in g mol$^{-1}$): ribose = 150, 2-deoxyribose = 134, glucose = 180; Atomic mass (in amu): H = 1, O = 16- JEE Advanced - 2025

- At 300 K, an ideal dilute solution of a macromolecule exerts osmotic pressure that is expressed in terms of the height (h) of the solution (density = 1.00 g cm$^{-3}$) where h is equal to 2.00 cm. If the concentration of the dilute solution of the macromolecule is 2.00 g dm$^{-3}$, the molar mass of the macromolecule is calculated to be $X \times 10^{4}$ g mol$^{-1}$. The value of $X$ is ____. Use: Universal gas constant (R) = 8.3 J K$^{-1}$ mol$^{-1}$ and acceleration due to gravity (g) = 10 m s$^{-2}\}$
