If 0.0714 moles of N2 gas occupies 1.25 L space, how many moles of N2 have a volume of 25.0 L? Assume temperature and pressure s
vfiekz [6]

Answer:

1.428 moles

Explanation:

If 0.0714 moles of N2 gas occupies 1.25 L space,

how many moles of N2 have a volume of 25.0 L?

Assume temperature and pressure stayed constant.

we experience it 0.0714 moles: 1.25L space

x moles : 25L of space

to get the x moles, cross multiply

(0.0714 x 25)/1.25

1.785/1.25 = 1.428 moles

In the reaction N2O4(g) 2NO2(g), what changes in color would you expect as pressure is increased at constant temperature?
skelet666 [1.2K]

Answer:

Brown color of the solution decreases

Explanation:

NO_2 is brown in color whereas N_2O_4 is colorless.

Equilibrium reaction between NO_2 and N_2O_4 is as follows:

2NO_2\leftrightharpoons N_2O_4

As per the Le Chatelier's principle, if pressure of a equilibrium is increased, the equilibrium will shift in the direction having fewer no. of moles of gases.

In the given equilibrium, NO_2 side has more no. of moles. So on increasing pressure, equilibrium will shift towards the side of N_2O_4 or more formation of N_2O_4 will take place.

Therefore, more NO_2 will decompose that will decrease the brown color of the solution as N_2O_4 is colorless.

How long will it take a plane to go 800 miles if it’s traveling at an average speed of 650 miles per hour?
Naya [18.7K]

If there is NO wind resistance, just plain math, this is the answer.

To get the answer you would divide 800 by 650.

800/650 = 1.230769231 (exactly)

That would translate to exactly <span>1 hour 13 minutes and 50 seconds </span>
