a) \(NaClO+HCl\dashrightarrow\)

b) \(NaOH+KHSO_4\dashrightarrow\)

c) \(FeCl_3+Na_2CO_3+H_2O \dashrightarrow\)

d) \(Si+NaOH+H_2O\dashrightarrow\)

e) \(C_6H_5OH+Na\dashrightarrow\)

Answer 1

a) TH1: \(NaClO+HCl\text{ (loãng)}\rightarrow NaCl+HClO\)

TH2: \(NaClO+2HCl\text{ (đặc)}\rightarrow NaCl+Cl_2\uparrow+H_2O\)

b) \(NaOH+2KHSO_4\rightarrow Na_2SO_4+K_2SO_4+2H_2O\)

c) \(2FeCl_3+3Na_2CO_3+3H_2O\rightarrow2Fe\left(OH\right)_3\downarrow+3CO_2\uparrow+6HCl\)

d) \(Si+2NaOH+H_2O\rightarrow Na_2SiO_3+H_2\uparrow\)

e) \(2C_6H_5OH+2Na\rightarrow2C_6H_5ONa+H_2\uparrow\)
