3. An element has two isotopic forms. One has a mass of 37 amu and one has a mass of 40 amu. If the average atomic mass of the element is 39 amu, what can be stated about the relative abundance of each isotope?

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.

Reducing agents  oxidized by the reaction 

Theyre semiconductors.
