2.15 moles of oxygen occupies 650 mL. How many moles of oxygen would be present if the volume were 1300 ml, assuming pressure and temperature remain
constant?

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
