you are throwing a birthday party for 11 guests (12 including yourself). each guest will probably eat 3 slices of birthday cake. each cake cost $12 and can be cut into 15 slices. how much will you have to spend to make sure there is enough cake for everyone at the party?

Ithink 2 is the correct

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.

Ibelieve the answer is weathering,hope my answer has you : ) 

D. h2o + h2o > h3o + oh- confirmed.
