Em tham khảo nha:
\(\begin{array}{l}
a)\,Fe + CuS{O_4} \to FeS{O_4} + Cu\\
b)\,2Al + 3CuC{l_2} \to 2AlC{l_3} + 3Cu\\
c)\,FeC{l_3} + 3KOH \to Fe{(OH)_3} + 3KCl\\
e)\,AgN{O_3} + NaCl \to AgCl + NaN{O_3}\\
f)\,{K_2}C{O_3} + Ca{(OH)_2} \to CaC{O_3} + 2KOH\\
g)\,CuS{O_4} + 2NaOH \to Cu{(OH)_2} + N{a_2}S{O_4}\\
h)\,N{a_2}S{O_4} + CaC{l_2} \to 2NaCl + CaS{O_4}\\
i)\,Ba{(N{O_3})_2} + N{a_2}C{O_3} \to BaC{O_3} + 2NaN{O_3}\\
j)\,CaC{O_3} + 2HCl \to CaC{l_2} + C{O_2} + {H_2}O
\end{array}\)
a / Fe + CuSO4 → FeSO4 + Cu
b/ 2Al + 3CuCl2 → 2AlCl3 + 3Cu
c/ FeCl3 + KOH → Fe(OH)3 + KCl
e / AgNO3 + NaCl → AgCl + NaNO3
f/ K2CO3 + Ca(OH)2 → CaCO3 + 2KOH
g/ CuSO4 + NaOH → Cu(OH)2 + Na2SO4
h/ Na2SO4 + CaCl2 → 2NaCl + CaSO4
i/ Ba(NO3)2 + Na2CO3 → 2NaNO3+ BaCO3
j/ HCl + CaCO3 → CaCl2 + H2O + CO2
