Question

write 2 equations of displacement reaction,double-displacement reaction,oxidation reaction and reduction reaction.

Answer 1

displacement reaction--
Zn+2HCl----> ZnCl+H^{2} [/tex] .

Zn+$H_{2}$S---> $H_{2}$+ZnS.



DOUBLE DISPLACEMENT REACTION---
$Na^{2}$$SO_{4}$+Ba$Cl_{2}$---> Ba$SO_{4}$+2NaCl.

NaOH+HCl--->NaCl+ $H_{2}$O.



OXIDATION REACTION AND REDUCTION REACTION::
2PbO+C--> 2Pb +$CO_{2}$

CuO+$H_{2}$--> Cu+$H_{2}$O.


HOPE THIS HELPS U.

Answer 2

Displacement Reaction
Mg + CuSO4 -------> MgSO4 + Cu
Zn + CuSO4 --------> ZnSO4 + Cu

Double Displacement reaction
AgNO3 + NaCl -------> AgCl + NaNO3
HCl + NaOH ---------> NaCl + H2O

Oxidation Reaction and Reduction Reaction
