1) is magnesium metal and hydrochloric acid solution an acid-base and single displacement reaction? Or just acid-base? Or just single displacement? 2) Is water an oxidation-reduction reaction?

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 velocity would be 2 

Are there any options that could alot..
