In addition to the structure below, how many other resonance forms are needed to correctly describe the symmetry of the carbonate anion, (CO32- ) ? (Consider only resonance contributors that have an octet at C and formal charges that do not exceed +1.)

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.

Answercreating graphs and performing calculations;
