The answer is (4) solid to gas. The entropy is the measurement of disorder. The entropy of CO2 under different status will increase from solid to liquid to gas. So the answer is (4).
Answer:
A location that is humid, would most likely support a marsh ecosystem.
Explanation:
The Florida Everglades are an example of a marsh :)
"Marshes are a type of wetland ecosystem where water covers the ground for long periods of time. Marshes are dominated by herbaceous plants, such as grasses, reeds, and sedges."
Answer:-
Option 2
Explanation:-
In a multi step reaction, the overall reaction is as fast as the slowest step only.
So the rate of a multistep reaction is the same as the rate of its slowest step.
The gas phase reaction was found to be second order wrt NO2.
So the slowest step must have 2 NO2 since the dependence is second order on NO2.
It was also found to be zero order wrt CO.
So the slowest step must not contain any CO since it’s presence has no effect on the reaction (zero order).
Among all options, only number 2 meets the two criterion
Thus the steps are
NO2 + NO2 – NO3 + NO (Slow)
NO3 + CO – NO2 + CO2 (Fast)
First determine the molality of the solution. m = (w solute)/[(mm solute)(kg solvent)] -- mm means molar mass. So,
m = (14.7 g)/[(180 g/mol)(0.150 kg) =0.544 mol/kg = 0.544 m
Change in boiling point (∆t) = m x Kbp = (0.544 m)(0.512 °C/m) = 0.28°C
The solution will boil at 100.28°C at 1 atm.
the density if water is 1.00 g/ml and Kb= 0.512 C/m
