What number do I change the 9 to so it's balanced?

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

here are some of the ways in which chemical and nuclear reactions differ.

explanation:

50.23 i believe is correct but don't quote me on that.
