heya mates!!
here goes the question for 10points..
please do answer :-)


give two equations as example of each of the following type of reaction
i) Combination reaction
ii)Decomposition reaction
iii)displacement reaction
iv)double displacement reaction
v)oxidation
vi)reduction​

Answer 1

Answer:

a. Mg + O2 - MgO

b. CaCO3 - CaO + CO2

c. Fe + CuSO4 - FeSO4 + Cu

d. Na2SO4 + BaCl2 - BaSO4 + NaCl

e. Cu + O2 - CuO

f. CuO + H2 - Cu + H2O

Answer 2

Combination Reaction:�If in a Chemical equation, two or more reactants combine to form a single product then it is known as combination reaction. ... Displacement Reaction:�If in a chemical equation, more reactive elements displaces a less reactive element from its compound then it is known as displacement reaction.

Combination reaction:-The reaction in which two or more elements or reactants react together to form a single product with entirely different properties is called combination reaction. Decomposition reaction:-The reaction in which single element breaks down to give two or more products is called decomposition reaction.
