The graph above shows data from a scientific study measuring the heart rate of daphnia in different water temperatures. Researchers in the study want to test the heart rate of daphnia at 90 F. Based on the data which of the following is the best prediction of Daphne has heart rate at 90 F? a. 100 BPM
B. 125 BPM
C. 148 BPM

D. 210 BPM

A.(nh4)(2co3)is the correct answer 

Sorry i dont understand the question can you rephase it?

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.
