(2011年浙江湖州,37题)2010年全国两会期间,与会人员领到的会议通知、日程表、便签纸等都是外观与普通纸相似的“石头纸”。“石头纸”的主要原料为碳酸钙,加上少量聚乙烯和胶合剂制成(聚乙烯和胶合剂不溶于水且不与盐酸反应)。

(1)“石头纸”中的碳酸钙属于     (选填“单质”、“氧化物”、“酸”、“碱”或“盐”)。

(2)为恶劣测定某种“石头纸”中碳酸钙的质量分数,某同学取该种“石头纸”样品10克,加入100克7.3%的盐酸溶液充分反应。反应后烧杯内剩余物质的总质量为106.48克;经过滤干燥后称得固体残渣质量为2克。

该同学想出甲、乙、丙三种计算方案:

甲:根据“反应后烧杯内剩余物质的总质量106.48克,可知二氧化碳的质量,……”求解;乙:根据“反应后经过了干燥后称得固体残渣的质量2克,可知样品中碳酸钙的质量,……”求解;

丙:根据“100克7.3%的盐酸溶液,可知参加反应的氯化氢质量,……”求解。

以上方案中,不正确的是     

(3)根据上述的某个正确方案计算该“石头纸”中碳酸钙的质量分数。

如图所示,将纯Fe棒和石墨棒插入1L 饱和NaCl溶液中.下列说法正确的是(  )

A.去掉电源,将M、N用导线直接相连,则Fe棒上产生气泡

B.M连接电源正极,N连接电源负极,则Fe棒被保护不会溶解

C.M连接电源负极,N连接电源正极,当两极产生气体总量为 22.4mL(标准状况)时,则生成0.001mol NaOH
