Question

CuSO4 + NaOH =  ... + ....
Na2CO3 + CaCl2 = ... + .....
Zn(OH)2 + HNO3 = ... + ...,
помогите пожалуйста

Answer 1

$Na_2CO_3+CaCl_2rightarrow 2NaCl+CaCO_3downarrow$

$Zn(OH)_2+2HNO_3rightarrow Zn(NO_3)_2+2H_2O$

Answer 2

CuSO₄ + 2NaOH = Cu(OH)₂ + Na₂SO₄
Na₂CO₃ + CaCl₂ = CaCO₃ + 2NaCl
Zn(OH)₂ + 2HNO₃ = Zn(NO₃)₂ + 2H₂O
