While Dr. Viraf J. Dalal’s Simplified Middle School Chemistry
10. Final Checklist Before Exams
- [ ] All chapter-end exercises solved and checked.
- [ ] Diagrams practiced (labeled).
- [ ] Valency table memorized.
- [ ] Chemical formulae of 50+ compounds memorized.
- [ ] 5 balanced equations per chapter.
- [ ] Definitions of 20+ key terms (e.g., diffusion, sublimation, alloy, oxidation).
- Solutions cover: Interconversion of states, sublimation examples (camphor, naphthalene), and conditions for chemical change.
- Key solved problems: Distinguishing between evaporation and boiling; explaining why burning of paper is a chemical change.
3.2 Integration of Practical Work The solutions include answers to laboratory-based questions (e.g., “How would you separate a mixture of sand, common salt, and ammonium chloride?”). By explaining sublimation, dissolution, filtration, and evaporation sequentially, the solutions bridge theory with hands-on experimentation.
Carbon and its Compounds: Examines allotropes like diamond and graphite, and the properties of carbon dioxide and monoxide. Key Features of the Solutions
9. Frequently Asked Questions
Q: Are Viraf Dalal’s solutions enough for ICSE exams?

1. Matter: Physical and Chemical Changes
This chapter revisits the basics of states of matter and dives into the distinction between physical changes (e.g., melting of ice) and chemical changes (e.g., rusting of iron).
Chemistry in the Dalal series is framed as the "law of nature" occurring in everyday life .
