Question: Given: H2O(l)→H2O(g),ΔH°=40.7K at 373 KWhat is the entropy change in the system ( ΔS ) when one mole of water vaporizes at 100°C and a pressure of one atmosphere?Hint ΔSsystem+ΔSsurrounding =Δ...
What is the entropy change in the system during the freezing of a substance if the following data is given: the molar heat capacity of the liquid state, Cp,m(l), is 75.3 J/Kmol; the molar heat capacity of the solid state, Cp,m(...
Dear Vickie, What a horrible attitude you have towards Chinese people. I feel your bigotry in your writing They are good human beings, not 'these people' and what a crass and humanless attitude you have to state something like "Is this another way for them to curb the population?" How ...
No matter how advanced a filtration technology is it still damages the structure of the water. Vortexing water is the solution to that. Last but not least, ‘bulk water’, which is essentially tap water that was made safe to drink but still contains a large amount of TDS is not the ...
At 25.8°C water has a vapor pressure of 24.912 torr. What is the mole fraction of water vapor at 25.8°C if Patm is exactly 1 atm? Dalton's Law of Partial Pressures: According to Dalton's law of partial pressures, the total pressure o...
complexified by environmental mechanisms. While this review is by no means exhaustive, many of the issues central to the state of the art of prebiotic chemistry are reviewed here. Introduction “Prebiotic chemistry” can be understood to mean various things: chemistry which occurred before life ...
We then introduce realizability of RNs by sum formulas and structural formulas as a first step towards a formalization of chemistry-like networks, and show that conservation of matter is already sufficient to guaran- tee the existence of such chemistry-like representations. Finally we discuss the ...
