The question seems to be incomplete. To calculate the work done in a chemical reaction, we need more information such as the change in volume, pressure, and temperature. The work done in a chemical reaction can be calculated using the formula w = -PΔV, where P is the pressure and ΔV is the change in volume. However, without these values, we cannot calculate the work done.

Also, whether the work is done on or by the system depends on the direction of the heat flow. If heat is flowing out of the system (exothermic reaction), then work is done by the system. If heat is flowing into the system (endothermic reaction), then work is done on the system.

In the case of the explosion of a hydrogen balloon, it is an exothermic reaction, so work is done by the system. But to calculate the exact amount of work done, we need more information.
