NCERT Solutions for Class 10 Science Chapter 1

Students who are weak in studies find science subjects confusing and challenging. Sometimes you find it challenging to understand the chemical symbols and chemical equations. Chapter 1 of science is full of theories and different types of chemical equations and reactions, which makes it confusing for you to understand the chapter without proper notes and study material. The equations are sometimes difficult to understand and bars you from securing good marks in the exams. The best way to get hold of the chapter is by practising the important question.

Skeltal chemical equation are unbalanced. We need to balance chemical equation because of law of conservation of mass. Therefore chemical equation must be balanced in each and every chemical reaction. It is also called double displacement reaction. They take CO 2 at night and is stored in the form of acid and is used during day time for photosynthesis. A Name the type of chemical reaction represented by the following equation: Answer.

These detailed solutions are prepared by our experts at Embibe and will help you score better in your exams. Class 10 Science is a very important subject. You will learn how substances react with each other to form new substances with new properties and how these changes are represented by chemical equations. There are many types of chemical reactions. Substances can combine to form a new substance or decompose to form new substances. Different compounds can also be formed by displacing an element in another substance or by exchanging elements. All of these chemical reactions involve the release or absorption of energy.
