Question

Class 10 important questions for science – chemical reactions and equations

Answer 1

the important questions for Science are the chemical reactions the types of reactions like decomposition displacement double displacement synthesis reaction oxidation reduction processes and all these types of reactions then exothermic and endothermic reactions remember that the examples are must because without an example in reaction you cannot score good marks then corrosion and rancidity are the main topics for the end of the chapter addition of Oxygen and removal of hydrogen all these come under the sub topic of oxidation the decomposition reaction and its for the types thermal decomposition electrolytic decomposition and photodecomposition I must balancing equations is the thing I must not forget to tell you the ionic equations the partial equation method of balancing chemical equations all are important but nothing is complete without the examples and that you can find a lot of in your extra book or in the NCERT
