Question

Записать уравнения возможных реакций в ионном и молекулярном видах: AgNo3+HCL-> , H2SO4+NaOH-> , Na2S+H2SO4-> , BaSO4+HCL->

Answer 1

AgNO3 + HCl -> AgCl↓ + HNO3
Ag(+) + NO3(-) + H(+) + Cl(-) -> AgCl↓ + H(+) + NO3(-)
Ag(+) + Cl(-) -> AgCl↓

H2SO4 + 2NaOH -> Na2SO4 + 2H2O
2H(+) + SO4(-2)+ 2Na(+) + 2OH(-) -> 2Na(+) + SO4(-2) + 2H2O
2H(+) + 2OH(-) -> 2H2O

Na2S + H2SO4 -> Na2SO4 + H2S↑
2Na(+) + S(-2) + 2H(+) + SO4(-2) -> 2Na(+) + SO4(-2) + H2S↑
2H(+) + S(-2) -> H2S

BaSO4 + 2HCl -> реакция не идёт

Answer 2

Ion Reactions:

The possible ion reactions for the given equations are as follows:

1. AgNO3 + HCl -> - Ag+ + NO3- + H+ + Cl- -> AgCl + HNO3 2. H2SO4 + NaOH -> - H+ + SO4^2- + Na+ + OH- -> H2O + Na+ + HSO4- 3. Na2S + H2SO4 -> - 2Na+ + S^2- + H+ + SO4^2- -> Na2SO4 + H2S 4. BaSO4 + HCl -> - Ba^2+ + SO4^2- + H+ + Cl- -> BaCl2 + H2SO4 Please note that these equations represent the ion reactions in the given molecular form.
