在探究“水的沸腾”实验中，下列说法正确的是（　　）

A．开始加热时，内部就有大量的气泡产生

B．开始加热时，有少量气泡，上升过程中越来越大

C．沸腾过程中，有大量的气泡，上升过程中体积变小

D．沸腾过程中，有大量的气泡，上升过程中体积变大，到达水面破裂

物质	NaCl	MgCl2	AlCl3	SiCl4
沸点/℃	1465	1412	181（升华）	57.6

①从表中的数据，结合学过的化学知识，你能得到的规律是                       。

②以上四种物质中，属于共价化合物的是                       。

③若你得到的规律具有普遍性，则以下两种物质的沸点高低是：LiCl   BCl₃（填“>”、“==”、“<”）。

（2）在密闭容器中，将1.0mol CO与1.0mol H₂O混合加热到800℃，发生下列反应：

CO（g）+H₂O（g）CO₂（g）+H₂（g）

一段时间后该反应达到平衡，测得CO的物质的量为0.5mol。

回答下列问题：

①平衡时CO的转化率为           ，该反应的化学平衡常数为           。

②如果继续向该平衡体系中通入1.0mol的H₂O（g），相同条件下反应达到新的平衡状态，则CO的转化率将            （填“增大”、“减小”、“不变”），预计CO的转化率为         。

③427℃时该反应的平衡常数为9.4，请结合①中的计算结果判断该反应的△H   0（填“>”、“==”、“<”）。
