Answer the following question about NH3 A) Difference in state—How does the compound’s use change in a different physical state or when mixed with other compounds at different concentrations? B) Difference in the reactivity of the compound with the reactivity of a similar compound—Does more or less reactivity change the way in which it is used? C) Change in the heat of reaction—Discuss the effects of changing the reaction temperature; for example, would the change make it unsafe, too slow,...
