Chemical compounds undergo both physical and chemical changes. Which of the following is an example of a physical change?

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.

The answer is c - the principal of original lateral continuity. 

Are you going to give an example of the plant or?
