問題詳情：

如圖為一“鐵鏈”圖案,小明在圖案上分別寫了H2、CO2、Na2O、NaCl、FeCl3五種物質,圖中相連的兩種物質均可歸屬為一類,相交部分A、B、C、D為其相應的分類依據代號。請回答下列問題:                                                                                                                              

(1)請將分類依據代號填入括號內:               兩種物質都不是電解質                                                                                                                       

(2)用潔淨的燒杯取少量蒸餾水,用酒精燈加熱至沸騰,向燒杯中逐滴加入1 mol·L-1圖中某物質M的水溶液,繼續煮沸可製得一種紅褐*液體。                                                                                                                    

①物質M的化學式為　　　　　　　　　　　　。                                                                                                                  

②*所製得的紅褐*液體是膠體的實驗*作是                                 　。                                                                                                                                   

（3）下圖是硫*試劑瓶標籤上的內容：                                                                                                                           

①該硫*的物質的量濃度是______         __mol·L－1。                                                                                                           

②某化學興趣小組進行硫**質的實驗探究時，上述硫*進行稀釋的實驗*作為                                                                                                                 

                                                                              。

【回答】

(1)A　(2)①FeCl3　②用一束光照*燒杯中的液體,若能產生丁達爾效應,則*生成了Fe(OH)3膠體                                                                                                                           

（3）①18.4 mol·L－1  ②將濃硫*沿著燒杯壁緩慢注入水中，同時用玻璃棒快速攪拌
