Question

помогите составить ионно-молекулярные и молекулярные уравнения:

а)Hg(NO3)2 + NaOH → HgО +

Б)CH3COONa + H2SO4 →

Answer 1

Hg (NO3)2 + 2NaOH→2NaNO3 + HgO+ H2O

2CH3COONa+H2SO4=2CH3COOH + Na2SO4

Answer 2

$Hg(NO_3)_2 + 2NaOH = HgO + 2NaNO_3 + H_2O\Hg^{2+}+2NO_3^-+2Na^++2OH^-=HgO+2Na^++2NO_3^-+H_2O\Hg^{2+}+2OH^-=HgO+H_2O$

$2CH_3COONa + H_2SO_4 = 2CH_3COOH + Na_2SO_4\2CH_3COO^-+2Na^++2H^++SO_4^{2-}=\=2CH_3COOH+2Na^++SO_4^{2-}\CH_3COO^-+H^+=CH_3COOH$
