The observed first-order rate of decay of carbon-14 in living material is 13.6 counts per minute per gram of carbon. An old wooden cup was discovered and found to give 10.9 counts per minute per gram of carbon. If the half-life of C-14 is 5730 years, approximately how old is the cup

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.

B. nuclear reactions could first occur.
