Maya smiled. She wrote confidently: Combination reaction. Iron + Oxygen → Iron(III) oxide. The increase in mass is due to the added oxygen from the air.
Suddenly, the concept clicked. She opened the solution book again — not to copy, but to her own answers to 10 practice questions. Each time, the solutions explained the reason , not just the final line. viraf j dalal chemistry class 8 icse solutions
Maya reluctantly opened to . She found the exact question: “Q. 4(c) – Explain with an example why the mass increases in some chemical changes.” Maya smiled
She scored in Chemistry — her highest yet. Moral of the story: Viraf J. Dalal’s ICSE Chemistry solutions for Class 8 aren’t just answer keys — they are reasoning guides. Use them after trying a problem yourself, to check your logic, understand the “why,” and build exam confidence. They turn confusion into clarity, one balanced equation at a time. If you need, I can also list specific chapters or common tricky questions from that book with explanations. Just let me know. The increase in mass is due to the added oxygen from the air
Here’s a helpful short story that illustrates how a student might use Viraf J. Dalal’s ICSE Chemistry for Class 8 to overcome a common struggle. Maya stared at the periodic table on her wall. It was 10 PM. Her ICSE Class 8 Chemistry exam was in two days, and she had hit a wall.
The topic? Physical and Chemical Changes — specifically, why a rusted nail weighed more than a new one. Her textbook said: “Rusting is oxidation. Iron combines with oxygen to form iron oxide.” But in her head, that made no sense. If something rusts and flakes away, shouldn’t it weigh less ?
