Differentiate between combination reaction and displacement reaction
Answers
combination reaction is a reaction in which two or more substances combine to form a single substance. ... Displacement reaction is a reaction in which a higher reactive element displaces a lesser reactive element and takes its place.
Explanation:
Direct combination reaction - When two substances react chemically to form a new substance which is a compound, it is a direct combination reaction.
Example - H_2+O\ →\ H_2O
Decomposition reaction - When a compound breaks up or decomposed into two or more substances which are simpler and can sustain independently. Example - Copper carbonate → Copper oxide + Carbon dioxide CuCO_3\ →\ CuO+CO_2
Displacement reaction: When an element displaces another element in a compound during a chemical reaction, it is a displacement reaction.
Example - 2AgNO_3+Cu\ →\ 2Ag+Cu(NO_3)_2\
Neutralization reaction : When an acid and a base react together to form salt and water, it is a neutralization reaction.
Example - NaOH+HCl\ →\ NaCl+H_2O
