210 questions are really tough to get from the chapter 'Chemical Reaction and Equation'.  Meanwhile, you can subscribe to topperlearning where you can get a question bank of all the chapters of Chemistry. Also, if you have any doubts about 'Chemical Reaction and Equations', you can post it in 'Doubts and Solutions' where our experts will get back to your queries. But you can get these five questions below which are important.
 
1. What happens in a displacement reaction? Justify your answer giving one example.
2. Why is electrolysis of water an endothermic reaction?
3. When potassium chlorate (KClO3) is heated in the presence of manganese dioxide catalyst, it decomposes to form potassium chloride and oxygen gas. Represent this in the form of a balanced chemical equation.
4. Write the balanced chemical equation for reactions that take place when lead nitrate and potassium iodide solutions are mixed.
5. Write a balanced chemical equation for a chemical combination reaction.
