Question

1 NaCl + H₂SO4 → HCI + Na₂SO4 2 CUSO + KOH → Cu(OH)₂ + K₂SO 3 ZnO + HNO₂ → Zn(NO3)₂ + H₂O 4 Ca + O, → Cao 5 Al + Cl₂ → AICL 6 CuO + HCI → CuCl, + HyO 7 NiCl₂ + NaOH → Ni(OH)₂ + Na Al+S → ALS 3 8 următoarelor reactii chimice:​

Answer 1

Răspuns:

Explicație:

2NaCl + H2 SO4= Na2 SO4 + 2 HCl

CuSO4 +2 KOH= K2SO4 + Cu (OH)2

Zn O +2 HNO3= Zn(NO3)2 + H2 O

2Ca+ O2= 2 CaO

2Al +3 Cl2= 2AlCl3

CuO + 2HCl= CuCl2 + H2 O

NiCl2 + 2NaOH= Ni(OH)2 +2 NaCl

2Al + 3S= Al2 S3
