explain combination reaction and decomposition reaction with example also balance the given
reaction
Ca(OH)₂ + HCl −−> CaCl₂ + H₂O
Answers
Answer:
Combination reaction is the reaction in which two substances combine to form a single product. Ex :- 2C +O2= 2CO Decomposition reaction is the reaction in which two substance in their aqueous state combine to form two new substance by the mutual exchange of their ions. Ex:- NaOH +HCl = H2O + NaCl
Answer:
combination reaction:- the reaction in which 2 or more 2 different types of element or compounds react with each other and form a single product.
e. g. 2Na+ Cl2= 2NaCl
( Note you will not write equal to sign in your copy, you will make an arrow instead of it)
decomposition reaction :- the reaction in which a single compound breaks down to give 2 or more than 2 elements or compound in the presence of heat or light or electricity is called decomposition reaction.
e. g. NH4Cl= NH3+HCl
Ca(OH) 2+2 HCl--> Cacl2+2H2O
