Mass Conservation Set 質量保存實驗器 P-4
如圖所示, 把兩種化學藥品放於實驗器中, 在實驗前先量度重量, 然後將器中之化學藥品傾倒使其完全發應過後, 再量度其重量你會發覺前後重量不變; 此證明質量保存定律是正確. 4 個透明耐酸鹼實驗器 容量 container volume 900mL 盛鹽酸小樽 dimension of bottle 90 x 180mm Dia. x H ,
容量８８g. 和炭酸氫鹽化學藥粉10袋（１ｇ／袋）
Containing carbonate chemical 10 package (1g/pack) , putting chemical pack into container and react with acid chemicals, the mass of whole bottle is the same as the mass of final experiment. to illustrate the mass is conservated during chemcial reaction. With 4 transparent acid resistance bottle 900mL and acid small container dimension of bottle 90 x 180mm Dia. x H
