B. OKCI
(aq)
--> KNO3(?) + AgCl()
C. NaCl
(aq) + KNO3(aq) --> NaNO3 (>) + KCI)
+ AgNO3(aq)
D
NH, Br
(aq)
+ KCI (aq) --> NH4Cl () + KBr (>)

D. is the answer hope that you

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."

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.
