物质与水发生复分解反应称为水解反应。例如：Al2S3+6H2O=2Al(OH)3↓+3H2S↑。根据上述观点，下列说法中不正确的是（  ） A、NaF的水解产物是NaOH和HF     B、CaOH2的水解产物是Ca(OH)2和H2O2 C、PCl3的水解产物之一是pH3             D、Mg3N2水解产物是Mg(OH)2和NH3 答案：（1）冰、生石灰、纯碱 CaO+H2O+Na2CO3=2NaOH+CaCO3↓       （2）第一个化学方程式不合理。 因为生成碳酸钙将与盐酸反应。       （3）3Mg(OH)2+2FeCl3=3MgCl2+2Fe(OH)3↓  因为Fe(OH)3 比Mg(OH)2更难溶。 It is well known that a judge, however, perhaps more than any other person, is ________ making and announcing his decision in public． [　　] A．proud of B．interested in C．accustomed to D．afraid of
