Question

write 5 chemical reaction of each type -
1.combination rxn
2.decomposition rxn.
3.displacement reaction.
4.double dispacment reaction
5.redox reaction
fast plzzzzz im in a hurry

Answer 1

combination reaction: Mg+O2----------2 MgO

decomposition reaction: H2O ---- H2+ O2


displacement reaction: Zn + CuSO4 -- ZnSO4 +Cu


double displacement: AgNO3 +NaBr -- AgBr + NaNO3


redox reaction: CuO + H2--- Cu + H2O


please mark me brainliest

Answer 2

1 . combination reaction:-
CaO +H2O ---------> Ca(OH)2
2.decomposition reaction :-
CaCO3 ---------> CaO +CO2
3. displacement reaction :-
Fe + CuSO4 -------> FeSO4 + Cu
4.double displacement reaction :-
Na2SO4 +BaCl2 -------> BaSO4 + 2NaCl
5.Redox reaction :-
ZnO + C -------> Zn + CO
