#### Solution Preview

The first step is to balance the reaction.

The reaction is:

4HCl+O_2 = 2H_2O+2Cl_2

So as you can see that one mole of O_2 (The native state of ...

#### Solution Summary

The expert balances a reaction equation and calculates the reactant mass. How much hydrogen chloride could be reacted with the use of oxygen is determined.
