For such calculation, we apply Planck's equation:
E = nhc / λ; where n is the number of photons, h is the Planck's constant, c is the speed of light and λ is the wavelength of the light.
As is visible from the equation, energy and wavelength have an inverse relationship. Therefore, larger energy drops produce smaller wavelengths and smaller drops produce larger wavelengths.
Answer:
Gamma Rays
Gamma Rays-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.
Explanation:
Answer:
1. False
2. False
3. True
4. False
Explanation:
1. CBr4 is more volatile than CCl4 False
The molecular weight of CBr4 is is greater than the CCl4, therefore it has less tendency to escape to the gas phase. Also, the CBr4 has greater London dispersion forces compared to CCl4 since bromine is a larger atom than chlorine.
2. CBr4 has a higher vapor pressure at the same temperature than CCl4 False
For the same reasons as above, the vapor pressure of CBr4 is smaller than the vapor pressure of CCl4
3. CBr4 has a higher boling point than CCl4 True
Again, CBr4 having a molecular weight greater than CCl4 ( 331 g/mol vs 158.2 g/mol) is heavier and less volatile with a higher boiling point than CCl4.
4. CBr4 has weaker intermolecular forces than CCl4 False
Both molecules are non-polar because the dipole moments in C-Cl and C-Br bonds cancel in the tetrahedron. The only possible molecular forces are of the London dispersion type which are temporary and greater for larger atoms.
Answer:
Because the molecules of the mixture would be compact or bond together at room temperature. In this case, both gases will condense to form water (or ice, if the room temperature is prolonged) and such droplets of water will not cause a balloon to spontaneously explode at room temperature.
Explanation:
A mixture of hydrogen and oxygen will form water. Recall that the chemical formula for water is H₂O, where H represents Hydrogen and O represents Oxygen.
A balloon is a light (not thick) solid substance with a thin membrane when blown or filled with some elements or gases.
Room Temperature means cool or cold temperature. You already know that generally at room temperature, the molecules of any substance will stick together or will become less mobile (less spontaneous).
In this case, hydrogen gas and oxygen gas will go through a process called condensation - to form water - and then through the process called freezing - to form ice.
At room temperature, the gases will first change state (state of matter) from gaseous to liquid and then from liquid to solid.
This is why the balloon will NOT spontaneously explode.
