draw and explain different type of chemical reaction with chemical equation
Answers
Answer: Chemical reactions can be classified in following types:
→Combination Reaction
→Decomposition Reaction
→Displacement Reaction
→Double Displacement Reaction
→Oxidation and Reduction Reaction
Explanation:
Combination Reactions
A combination reaction, also known as a synthesis reaction, is a reaction in which two or more substances combine to form a single new substance. Combination reactions can also be called synthesis reactions .The general form of a combination reaction is:A+B→AB
for example:2Na(s)+Cl2(g)→2NaCl(s)
Decomposition Reactions
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.It is further divided into thermal, photolytic and electrolytic decomposition.The general form of a decomposition reaction is:AB→A+B
for example:2HgO(s)→2Hg(l)+O2(g)
Displacement Reactions
A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement (also called single-displacement) reaction is:A+BC→AC+B
for example:Mg(s)+Cu(NO3)2(aq)→Mg(NO3)2(aq)+Cu(s)
Double-Displacement Reactions
A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement (also called double-displacement) reaction is:AB+CD→AD+CB(5.3.12)
for example:2KI(aq)+Pb(NO3)2(aq)→2KNO3(aq)+PbI2(s)
other reactions include precipitation,redox, oxidation and reduction reactions.
