Question

Imi puteti rezolva si mie acestea va rog?
HNO3+KOH=....+.....
HNO3+MgCO3=....+....
HCL+CaCO3=....+.....
KOH+AlCl3=.....+....
NaOH+ZuBr2=....+....
HCl+ZuBr2=.....+....

Answer 1

=H2O+KNO3
=H2CO3+Mg(NO3)2...scrie tu in fata substantei HNO3 cifra 2
=H2CO3+CaCl2....scrie in fata subst. HCl cifra 2
=KCl+Al(OH)3....scrie in fata subst KOH cifra 3
=2NaBr+Zn(OH)2....scrie in fata subst NaOH cifra 2
=2HBr+ZnCl2.....scrie in fata subst HCl cifra 2

Answer 2

HNO3 + KOH --> KNO3 + H2O

2HNO3 + MgCO3 --> Mg(NO3)2 + H2CO3 (CO2 + H2O)

2HCl + CaCO3 --> CaCl2 + H2CO3(CO2+H2O)

3KOH + AlCl3 --> Al(OH)3 3KCl

2NaOH + ZnBr2 --> 2NaBr + Zn(OH)2

HCl + ZnBr2 --> ZnCl2 + 2HBr
