Class 10 Science — Chemical Reactions and Equations Important Questions with Answers (Long answers)
Class 10 Science is one board paper with chemistry, biology and physics stitched. Chemical equations, life processes, heredity, spherical mirrors, electricity and our environment are the high-traffic searches. This page replaces the old empty subject shell and the three-chapter demo with a full 150+ file bank in the Class 9 style: hidden answers, twenty questions a page, rationalized 2023–26 chapter names only. Use it as a daily test, not as a date rumour about the board.
Chemical Reactions and Equations — रासायनिक अभिक्रियाएँ एवं समीकरण
Balancing is conservation of atoms, not decoration. Combination, decomposition, displacement, double displacement and redox are the five labels. Corrosion and rancidity are everyday redox. A skeletal equation that is not balanced is not a finished Class 10 answer. Write states if the book example does; otherwise keep atoms honest first. You are on Chemical Reactions and Equations (Long answers), page 1 of 1 — 1 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.

A skeletal equation that is not balanced is not a finished Class 10 answer. Write states if the book example does; otherwise keep atoms honest first.
चार बिंदु: (1) NCERT परिभाषा/सूत्र/घटना। (2) एक उदाहरण या आरेख-विचार। (3) एक तुलना या कारण। (4) एक साधारण संख्यात्मक या उद्धरण यदि पाठ माँगता है।
निष्कर्ष: उत्तर अध्याय-सत्य रखें — बोर्ड की डेटशीट यहाँ नहीं गढ़ी गई।
