Let's review, why do these elements need an source, such as the in this experiment, to glow? Electrons absorb the energy and jump to energy levels. When these electrons return to energy levels, they emit energy in the form of light called . Word Bank: photons, energy, flame, lower, higher, heat

Rn in the right answer

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.
