chemical reaction and Types of chemical reactions
Types of chemical reactions A chemical reaction is the process to involve the breaking and making or formation of chemical bonds between atoms to produce new substances is known as chemical reaction . A chemical reaction is the chemical transformation in which one type of substance which is reactants reacts chemically and converts into a new substances which is products. There are different types of chemical reaction :-- 1. Combination reaction:--- In this combination reaction, single products is formed from two or more reactants is known as combination reactions. Combination reactions is also called as synthesis reaction Example :-- CaO (s) + H 2 O (l) → Ca(OH) 2 (aq) + heat Here, calcium oxide and water Is combined to form a single product calcium hydroxide. Burning of coal:-- C (s) + O 2 (g) → CO 2 (g) Formation of water from H 2 (g)and O 2 (g) 2
