Question

Hoàn thành các PTPU

a)Na+ H2O -->

b)K + H2O -->

c)Ba + H2O -->

d)CaO + H2O --->

e)Fe(OH)₃ + HCl

f)Al(OH)₃ + H₂SO₄ -->

g)Ba(NO₃)₂ + HNO₃ -->

h)Mg(OH)₂ + HNO₃--->

i)CuSO₄ + NaOH

Answer 1

a) \(Na+H_2O\rightarrow NaOH+\dfrac{1}{2}H_2\)

b) \(K+H_2O\rightarrow KOH+\dfrac{1}{2}H_2\)

c) \(Ba+2H_2O\rightarrow Ba\left(OH\right)_2+H_2\)

d) \(CaO+H_2O\rightarrow Ca\left(OH\right)_2\)

e) \(Fe\left(OH\right)_3+3HCl\rightarrow FeCl_3+3H_2O\)

f) \(2Al\left(OH\right)_3+3H_2SO_4\rightarrow Al_2\left(SO_4\right)_3+6H_2O\)

g) Mình sửa HNO₃ thành H₂SO₄ nhá

\(Ba\left(NO_3\right)_2+H_2SO_4\rightarrow BaSO_4+2HNO_3\)

h) \(Mg\left(OH\right)_2+2HNO_3\rightarrow Mg\left(NO_3\right)_2+2H_2O\)

i) \(CuSO_4+2NaOH\rightarrow Cu\left(OH\right)_2+Na_2SO_4\)
