# The Ruskie Experiment

Chemistry Level 3

In a USSR gulag, a room full of prisoners is subjected to both tear gas ($$\ce{C10H5ClN2}$$) and laughing gas ($$\ce{N2O}$$). The laughing gas is released from the front of the room, and the tear gas is released from behind. If the room is full and has 20 benches, prisoners sitting on which bench number will be the first to both cry and laugh? (Assume that the benches are placed at a distance of 1 meter from each other)
