Interpretation:
The reason to connect water to a condenser so it flows in at bottom and out at top should be determined.
Concept introduction:
Many organic reactions are non-spontaneous and to proceed they require heat. The heating of reagents mixture in open containers causes evaporation of the compounds while heating in the close container can cause an explosion.
Explanation of Solution
The condenser is an apparatus that is used in the laboratory to cool the heated liquid. It is vertically mounted above reaction flask and provides a method to cool vapor so that it condenses and flows back in reaction flask.
The condenser is cooled by water or air. Therefore, water is connected to condenser so it can be ensured that there are no air bubbles and can efficiently cool the glass wall of the condenser.

Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by: 4C3H5N3O9(l)→6N2(g)+12CO(g)+10H2O(g)+7O2(g) A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 203 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 40% dynamite explodes?arrow_forward
