An aquarium 5 m long, 3 m wide, and 2 m deep is full of water. Find the work needed to pump half of the water out of the aquarium. (Use the fact that the density of water is 1000 kg/m3, and use 9.8 m/s2 for g.)

Question Detailsif A x B = B x C then C.A - C.B = c|A-B| yes or noand(AxB)x(CxB) = B(B.(CxA)) yes or no

2NO2(g) ---> N2O4(g)

Do you expect K>1 or K<1for this reaction? Why?

Dinitrogen tetroxide decomposes to nitrogen dioxide:
N₂O₄ -> 2NO₂

What is the missing information on the following table:

Time (microsec) [N₂O₄](M) [NO₂] (M)

0.000 0.050 0.000

20.00 0.033

40.00 0.050

60.00 0.020

I found the concentration of N₂O₄ at 40.00microseconds to be 0.025 M since this is a second order reaction.However, I am stuck trying to figure out the concetration of theproducts. Please help!

I used 1/[A] = kt + 1/[A]₀ to find the concentrationmentioned above.

Dinitrogentetroxide decomposes to nitrogen dioxide:
N2O4 (g)---> 2NO2 (g) Delta H rxn: 55.3 kJ

At 298 K areaction vessel initially containing .100 atm of N2O4. Whenequilibrium is reached, 58% of the N2O4 has decomposed toNO2.

-Whatpercentage of N2O4 decomposes at 350 K? Assume that the initialpressure of N2O4 is .100 atm.

For the decomposition of dinitrogen pentoxide in carbon tetrachloride solution at 30 °C

2 N₂O₅4 NO₂ + O₂

the average rate of disappearance of N₂O₅ over the time period from t = 0 min to t = 127 min is found to be 1.93×10^-3 M min^-1.

The average rate of formation of O₂ over the same time period is  M min^-1.
