Answer:
76.03 °C.
Explanation:
Equation:
C2H5OH(l) --> C2H5OH(g)
ΔHvaporization = ΔH(products) - ΔH (reactants)
= (-235.1 kJ/mol) - (-277.7 kK/mol)
= 42.6 kJ/mol.
ΔSvaporization = ΔS(products) - ΔS(reactants)
= 282.6 J/K.mol - 160.6 J/K.mol
= 122 J/K.mol
= 0.122 kJ/K.mol
Using gibbs free energy equation,
ΔG = ΔH - TΔS
ΔG = 0,
T = ΔH/ΔS
T = 42.6/0.122
= 349.18 K.
Coverting Kelvin to °C,
= 349.18 - 273.15
= 76.03 °C.
most metals conduct electricity and are very dull to the look. most metals are toxic if eaten and are hard.
aluminum is a type of metal they is softer than the opther and conducts eletricty like a boss.
nickel on the opther hand is also a metal but does not conduct a lot of electricy.
metals can be bent and others can break,
Answer:
Water's unique density, high specific heat, cohesion, adhesion, and solvent abilities allow it to support life.
Explanation:
The answer should be A. Because the energy in gasoline is called chemical. When burned it is heat, Then to power a vehicle, it is mechanical energy. But I don't know whether the question wants to mean that the energy in the gasoline will not convert totally to the heat, so it will lose. But if think like this, when heat energy transform to mechanical, it will lose again. So I think the answer is A.
In order to decrease the chances of deception in acquiring a handwriting sample, what the law enforcement do is that, they ask they person to write as little as possible, write the passage only once and also gather the material that consist some of the similar words and phrases as the suspected document. Answer for this would be all of the above.
