Question

Help me fast and don't write rubbish or i will report you ​

Answer 1

ANSWER:–

[1.] Decomposition Reaction

[2.] Displacement Reaction

[3.] Neutralisation Reaction

[4.] Combination Reaction

Answer 2

Answer:

1) CaCO3 = CaO + CO2 is a decomposition reaction. Decomposers reactions are those reaction in which single reactant forms two or more products.

2) Cu + 2AgNO3 = Cu( NO3)2 + 2Ag is a displacement reaction. Displacement reaction are those reactions in which more reactive metal displaces less reactive metal.

3)NaOH + HCL = NaCl + H2O is a double displacement reaction. Double displacement reaction are those reactions in which exchange of ions take place.

4)Fe + S = FeS is a combination reaction. Combination reactions are those reactions in which two or more reactants form single products..

Hope it's help ✌✌
