B. $MgNO_3$ and $H_2$
C. $Mg(NO_3)_2$ and $H_2O$
D. $Mg(NO_3)_2$ and $H_2$
参考答案: D
本题详细解析:
Metals and acids react to p z/ihbu:5+ rpzroduce a salt and hydrogen gas. The formulae of the ions arpz+u 5zhi :b/re $Mg^{2+}$ and $NO_3^{-}$, therefore for a neutral salt, two nitrate ions are required for each magnesium ion.
