Answer:
See explanation
Explanation:
The substance under analysis must be a polar organic substance of high molecular mass. We must remember that as the magnitude of dispersion forces increases with increase in molecular mass, the melting point increases accordingly. Also polar organic substances have very high melting points due to the presence of polar bonds in the molecule..
Hence the intramolecular forces in the substance are covalent bonds while the intermolecular forces are both dispersion forces and dipole forces.
The substance may likely be 1,2,3,4,6,7,8-Heptachlorodibenzo-p-Dioxin which a white powder and melts at 264 °C.
Answer:
Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation.
That answer is either 3 or 4, but I truly forgot which of the two.
Answer:
7604 kJ
Explanation:
Heat of vaporization for copper = 5069J/g (from my reference source. Use the value you were given).
(1,500grams)*(5069J/g) = 7603500 J, or 7604 kJ The latent heat of vaporization you are given may be slightly lower than the official value of 5069 J/g.
