The combustion of ammonia proceeds by the reaction           4 NH3    +    7 O2  →  4 NO2    +    6 H2O When the rate of appearance of H2O is 1.10 Ms-1, the rate of disappearance of O2 is          Ms-1

A sample of sodium bicarbonate, NaHCO3,  is placed in a closed 1.0 L vessel at 398 K and allowed to decompose unil it reaches equilibrium according to the following equation:                                         2 NaHCO3 (s)   ⇌  Na2CO3(s) +  H2O (g)   +  CO (g)      Kp = 0.450 What is the partial pressure of CO (in atm)  at equilibrium?

A warehouse filled with pallets of 3 ft3{“version”:”1.1″,”math”:”3 ft3″} bags of mulch must be completely emptied.  The warehouse contains a total of 1400 pallets that must be removed and placed onto trailers for distribution to retail stores.  The number of pallets remaining, P(t), is a function of the time spent moving pallets, t, in hours.  Work continues at a reasonably steady pace until all 1400 pallets are removed.  Using linear regression, the manager found the following algebraic representation for the function: P(t)=-111t+1400{“version”:”1.1″,”math”:”P(t)=-111t+1400″}. Use P(t) to predict the number of hours necessary to empty the warehouse.  Round to two decimal places if necessary. _______
