\(2Al+6HCl\Rightarrow2AlCl_3+3H_2\\ Mg+2HNO_3\Rightarrow Mg\left(NO_3\right)_2+H_2\\ C_2H_6O+3O_2\underrightarrow{t^o}2CO_2+3H_2O\\ 4P+5O_2\Rightarrow2P_2O_5\)
2Al(OH)3 → Al2O3 + 3H2O
Fe3O4 + 2C → 3Fe + 2CO2
1) H2SO4 + 2NaOH -> Na2SO4 + 2H2O.
2) H2SO4 + Mg(OH)2-> Mg(OH)2 +2H2O.
3)2HNO3 + Zn(OH)3 -> Zn(NO3)2 + 2H2O.
1. \(H_2SO_4\)+ NaOH --> \(Na_2SO_4\)+ \(H_2O\)
\(H_2SO_4\)+ 2NaOH --> \(Na_2SO_4\)+\(H_2O\)
\(H_2SO_4\)+ 2NaOH \(\rightarrow\) \(Na_2SO_4\)+2\(H_2O\)
2. \(H_2SO_4\)+ \(Mg\left(OH_2\right)\)--> \(MgSO_4\)+\(H_2O\)
\(H_2SO_4\)+\(Mg\left(OH_2\right)\)\(\rightarrow\) \(MgSO_4\)+2\(H_2O\)
3. \(HNO_3\)+\(Zn\left(OH\right)_3\)-->\(Zn\left(NO_3\right)_2\)+\(H_2O\)
2\(HNO_3\)+\(Zn\left(OH\right)_3\)-->\(Zn\left(NO_3\right)_2\)+\(H_2O\)
2\(HNO_3\)+\(Zn\left(OH\right)_3\)\(\rightarrow\)\(Zn\left(NO_3\right)_2\)+2\(H_2O\)

cac bạn ơi dấu bằng ong rồi cách ra làm cái khác nhé ình viết sai
chỉ có phần chất tham gia phản ứng thôi
