The picture shows the gas generator that produces ammonia in the laboratory. Please answer the following questions according to your knowledge: (1) The name of the instrument used for heating in the picture is _ _ _ _. (1) The name of the instrument used for heating is alcohol lamp. Ammonia is very soluble in water and cannot be collected by drainage. Ammonia gas is less dense than air and does not react with air, so it is collected by downward exhaust method. Ammonia reacts with water to produce ammonia water, which ionizes ammonium ions and hydroxyl ions, resulting in ammonia water being alkaline, and red litmus paper turns blue when it meets alkali, so ammonia gas can be detected by wet red litmus paper.

So, the answer is: alcohol lamp; Exhaust downward; Use wet red litmus paper near the bottle mouth. If it turns blue, it means the bottle is full.

(2) Under the heating condition, ammonium chloride and calcium hydroxide react to generate calcium chloride, ammonia gas and water, and the reaction equation is as follows.

2NH4Cl+Ca(OH)2？ △? . ? CaCl2+2NH3↑+2H2O。

So the answer is 2NH4Cl+Ca(OH)2? △? . ? CaCl2+2NH3↑+2H2O。

(3) Let the generated ammonia volume be VL.

2NH4Cl+Ca(OH)2？ △? . ? CaCl2+2NH3↑+2H2O？

107 g 44.8 l

5.35 g VL

V=2.24

So the answer is 2.24 l.
