Question

составить молекулярные и ионные уравнения
NO3+CuO

NO3+Cu(OH)2

NO3+NaOH

NO3+K2SO3

Answer 1

2HNO3+CuO=Cu(NO3)2+H2O
$2 H^{+} +2 NO_{3} ^{-} +CuO = Cu^{2+} + 2NO_{3}^{-} + H_{2}O 2H^{+}+CuO=Cu^{2+} + H_{2}O$
$2HNO_{3} + Cu(OH)_{2}=Cu(NO_{3})_{2}+2H_{2}O 2H^{+}+NO_{3}^{-}+Cu(OH)_{2}=Cu^{2+}+2NO_{3}^{-}+2H_{2}O 2H^{+}+Cu(OH)_{2} = Cu^{2+}+2H_{2}O$
$HNO_{3}+NaOH=NaNO_{3}+H_{2}O H^{+}+NO_{3}^{-}+Na^{+}+OH^{-}=Na^{+}+NO_{3}^{-}+H_{2}O H^{+}+OH^{-}=H_{2}O$
$2HNO_{3}+K_{2}SO_{3}=KNO_{3}+H_{2}O+SO_{2} 2H^{+}+NO_{3}^{-}+2K^{+}+SO_{3}^{-2}=K^{+}+NO_{3}^{-}+H_{2}O+SO_{2} 2H^{+}+SO_{3}^{-2}=H_{2}O+SO_{2}$
