Chemical Reactions and Equations: Class 10 Science (CBSE) important questions and practice
Chemical Reactions and Equations is chapter 1 of 13 in CBSE Class 10 Science. Below are the topics the paper draws from, the question types that come up again and again, and a free practice test on this chapter alone.
Topics in this chapter
- Writing and balancing chemical equations
- Types of reactions: combination, decomposition, displacement, double displacement
- Oxidation and reduction (redox) reactions
- Exothermic and endothermic reactions
- Corrosion and rancidity
- Effects of oxidation in everyday life
What examiners usually ask
- Balance the equation: Fe + H2O gives Fe3O4 + H2 and identify the type of reaction
- What is a double displacement reaction? Give an example with a balanced equation
- Why is respiration considered an exothermic reaction?
Exam tip
Always include state symbols and the heat/light conditions when balancing, and for the lead nitrate, ferrous sulphate and silver chloride decomposition reactions remember the colour changes examiners ask about.
