Напишите уравнения в молекулярно-ионном виде между веществами:а) гидроксидом меди(II)и...

А) $Cu(OH)_{2} + 2HCl = CuCl_{2} + 2H_{2}O Cu^{2+} + 2OH^{-} + 2H^{+} +2Cl^{-} = Cu^{2+} + 2Cl^{-} + 2H_{2}O 2H^{+} + 2OH^{-} = 2H_{2}O H^{+} + OH^{-} = H_{2}O$

б) $Al_{2}O_{3} + 6HNO_{3} = 2Al(NO_{3})_{3} + 3H_{2}O Al_{2}O_{3} + 6H^{+} + 6NO_{3}^{-} = 2Al^{3+} + 6NO_{3}^{-} + 3H_{2}O Al_{2}O_{3} + 6H^{+} = 2Al^{3+} + 3H_{2}O$

в) $Na + H_{2}SO_{4} = Na_{2}SO_{4} +H_{2} Na^{0} + 2H^{+} + SO_{4}^{2-} = 2Na^{+} + SO_{4}^{2-} + H_{2} Na^{0} + 2H^{+} = 2Na^{+} + H_{2}$
