Question

Помогите с ионными уравнениями
Sn+2HCl = SnCl2 + H2
SnCl2 + NaOH = SnOHCl + NaCl
SnOHCl + KOH = Sn(OH)2 + KCl
Sn(OH)2 + HNO3 = Sn(NO3)2 + HOH

Answer 1

Sn+2HCl = SNCl2 + H2

$Sn^{0} + 2H^{+} + 2Cl^{-} = Sn^{2+} + 2Cl^{-} + H_{2}^ {0}\\Sn^0 + 2H^+ = Sn^{2+} + H_2$

SnCl2 + NaOH = SnOHCl + NaCl

$Sn^{2+} + 2Cl^{-} + Na^{+} + OH^{-} = SnOH^{+} + Cl^{-} + Na^{+} + Cl{-}\\Sn^{2+} + 2Cl^{-} + OH^{-} = SnOH^{+} + Cl^{-} + Cl^{-}$

SnOHCl + KOH = Sn(OH)2 + KCl

$SnOH^{+} + Cl^{-} + K^{+} + OH^{-} = Sn(OH)2 + K^{+} + Cl^{-}\\SnOH^{+} + OH^{-} = Sn(OH)2$

Sn(OH)2 + 2HNO3 = Sn(NO3)2+ HOH

$Sn(OH)2 + 2H^{+} + 2NO_{3} ^{-} = Sn^{2+} + 2NO_{3} ^{-} + HOH\\Sn(OH)2 + 2H^{+} = Sn^{2+} + HOH$
