Can someone explain where the 2X came from? We weren't given a reaction or anything...

For every 1 molecule of X2, it decomposes to 2 molecules of X. That is why there is a coefficient of 2 in front of X.

To create a balanced chemical equation, X must have a stoichiometric coefficient of 2 (since the flask shows the diatomic molecule X2 decomposing into X atoms).
