Answer:
Explanation:
For second order reaction
dC / dt = -k C²
dC /C² = - kdt
Integrating on both sides,
[- 1/C ] = - kt + P , P is a constant .
When t =0 , C = 1.33 M
P = - 1 / 1.33
[- 1/C ] =- - kt - 1 / 1.33
When t = 8.5
[- 1/C ] = - kt - 1 / 1.33
= - 1.18 x 8.5 - 1 / 1.33
= - 10.03 - .7519
= - 10.782
C = .0927 M
= .093 M
Answer:
O.5 h
Explanation:
If it can travel 1224 kilometers an hour then traveling 612 would take half an hour to do.
A solution may exist in any phase so your answer is D. any of the above
hope this helps :)
Answer:
The pressure of N₂ gas in cylinder B when compressed at constant temperature increases due to the increase in the frequency of collision between the gas molecules with themselves and with the wall of their container caused by a decrease in volume of the container.
Explanation:
Gas helps to explain the behavior of gases when one or more of either temperature, volume or pressure is varying while the other variables are kept constant.
In the gas cylinder B, the temperature of the given mass of gas is kept constant, however, the volume is decreased by pushing the movable piston farther into the cylinder. According to the gas law by Robert Boyle, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature. This increase in pressure is due to the increase in the frequency of collision between the gas molecules with themselves and with the wall of their container caused by a decrease in volume of the container. As the cylinder becomes smaller, the gas molecules which were spread out further become more packed closely together, therefore, their frequency of collision increases building up pressure in the process.
From the coefficients of the equation, we see that for every 4 moles of aluminum consumed, 3 moles of oxygen are consumed.
So, the answer is (12/4)(3) = 9 moles.
