Answer:
C
Explanation:
The rate of a reaction decreases as time progresses. ... If the amount of reactant particles is decreasing as the reaction progresses, then the chance of successful collisions must also decrease, and ultimately when all the reactant particles have reacted, the reaction must stop and the rate become zero.
Condensation is when vapor liquidizes and gathers on top of a surface, while boiling is turning a liquid into a gas or vapor. They are opposites. In the first, the molecules of the substance split and separate and increase the volume, while in the second they come together and reduce the volume.
Answer:
50 kg benzene/hour and 25 kg toluene/hour
Explanation:
According to Lavoisier's law, the mass can't be created either destroyed, thus, the material in the input must be equal to the material in the output + the material formed if there's a reaction + the accumulation in the reactor.
Thus, for bezene:
minput = mtop + mbottom
If 50% of the mass is composed by each substance:
0.5*1000 = 450 + mbottom
500 = 450 + mbottom
mbottom = 50 kg benzene/hour
For toluene:
minput = mtop + mbottom
0.5*1000 = mtop + 475
mtop = 500 -475
mtop = 25 kg toluene/hour
Measurement is used to figure out height or width of an object
