Answer:
before it evaporated into the air, it was on the Earth...and it could have been contaminated/dirtied. There isn't a process during evaporation that cleans water...you have to purify it yourself.
Explanation:
Answer:
the answer is C) the iron will repel the substance because it has more electrons than protons
Answer:
(B) 2AgCl + sunlight → Cl2 + 2Ag (decomposition reaction) is correct option.
There are different techniques to reduce friction, similar to 1. Cleaning the surfaces 2. Including lubricants 3. expanding the temperature 4. wetting the surface 5. expelling polluting influences. Egyptian could have moved the square through water, which would be Fluid Friction, and makes it less demanding to move.
Answer is: entropy of evaporization of benzene is 86,7 J/mol·K.
T(benzene - C₆H₆) = 80,1 °C = 80,1 + 273,15 = 353,25 K.
ΔHvap(C₆H₆) = 30,7 kJ/mol.
ΔSvap(C₆H₆) = ?
ΔS(C₆H₆) = ΔH ÷ T
ΔS(C₆H₆) = 30,7 kJ/mol ÷ 353,25 K
ΔS(C₆H₆) = 0,087 kJ/mol·K = 86,7 J/mol·K.
ΔS - e<span>ntropy of evaporization.</span>
