Concept explainers
(a)
Interpretation:
Need to explain why the N2(g) extracted from liquid air do not have the same density as the N2(g) extracted from its compounds.
Concept introduction:
In the atmosphere, N2(g) is mixed with other gases.
(b)
Interpretation:
Need to explain which gas has greater density among N2(g) extracted from liquid air or N2(g) extracted from its compounds.
Concept introduction:
In the atmosphere, N2(g) is mixed with other gases while N2(g) from its compound is pure.
(c)
Interpretation:
Need to explain the significance of the experiment which Ramsay used to prove the N2(g) extracted from liquid air was itself a mixture of gases.
Concept introduction:
Ramsay’s experiment was very useful in identification of noble gases.
(d)
Interpretation:
Need to calculate the percent difference in densities at 0.00 C and 1 atm of Rayleigh’s N2(g) extracted from liquid air or N2(g) extracted from its compounds.
Concept introduction:
N2(g) extracted from liquid air do not have the same density as the N2(g) extracted from its compounds because N2(g) extracted from liquid air is mixed with noble gas − Ar.

- Hw.173.arrow_forwardA container with 0.2450.245 L of water is placed in a microwave and radiated with electromagnetic energy with a wavelength of 14.114.1 cm. The temperature of the water rose by 72.172.1 °C. Calculate the number of photons that were absorbed by the water. Assume water has a density of 1.00 g·mL−11.00 g·mL−1 and a specific heat of 4.184 J·g−1·°C−14.184 J·g−1·°C−1.arrow_forward5) Richard Feynman called the Euler relation the most remarkable formula in mathematics. Use the Euler relation to give the value of the following quantities. eio=1 ein/2_ ein = ei2π = (Hix = (rcosx = i sin x)arrow_forward
- It takes 151./kJmol to break an iodine-iodine single bond. Calculate the maximum wavelength of light for which an iodine-iodine single bond could be broken by absorbing a single photon. Be sure your answer has the correct number of significant digits.arrow_forwardSchrodinger and de Broglie suggested a ‘Wave—particle duality" for small particles—that is, if electromagnetic radiation showed some particle-like properties, then perhaps small punicles might exhibit same wave-like properties. Explain. How does the wave mechanical picture of the atom fundamentally differ from the Bohr model? How do wave mechanical arbitals differ from Bohr’s orbits? What does it mean to say that an orbital represents a probability map for an electron?arrow_forwardFor 1 I have A being B, B. No, C. Yesarrow_forward
- Narrate James Clerk Maxwell’s line of reasoning in linking electromagnetism to light by interpreting his four (4) equations.arrow_forwardWhich statement on planes is correct? Part of (300) planes are (100) planes. Part of (100) planes are (300) planes. There is no overlapping between (300) and (100) planes, (300) and (100) planes are identical.arrow_forward1. a) Calculate the numerical values of the energies of the first four energy levels in hydrogen in units of both joules (J) and in electron-volts (eV). The first four energy levels are found substituting n = 1, 2, 3, 4 into the equation you found in section (f) above. Show all work. b) Use r = n²ħ²/(e²km) to calculate numerical values for the radii of the first four allowed electron 'orbits' in hydrogen, in units of m. The radius of the 'orbit' closest to the nucleus is called the Bohr radius and is given the symbol ao. (You should notice that each radius is a multiple of the Bohr radius, ie. when n = 1 then r = ao, if n = 2 then r = 2² ao, at n = 3 then r = 9 ao, etc.) 1 2 3 4 c) Summarize your numerical results in the following table; Quantum number n Radius of electron's 'orbit' (m) Electron Energy (J) Electron Energy (eV)arrow_forward
- Convert S-2, Cl-1, Ar, K+1, Ca+2 to picometers and compare the results with teh radius of a hydrogen atom (52.9 pm). Is the hydrogen atom much larger of smaller than the wave.arrow_forwardImagine a particle free to move in the x direction. Which of the following wavefunctions would be acceptable for such a particle? In eachcase, give your reasons for accepting or rejecting each function. (i) Ψ(x)=x2; (ii) Ψ(x)=1/x; (iii) Ψ(x)=e-x^2.arrow_forwardSuppose that you have a solution containing a substance whose molecules have two quantum states corresponding to different orientations of a certain subgroup of atoms. The energy difference between these two molecular states is ΔE = 0.130 eV. You are running an experiment where no more than 5% percent of the molecules can be in the higher-energy state, or it will cause unacceptable noise. Can you run the experiment at room temperature, or do you need to cool your solution? Decide by determining the percentage of molecules in the higher-energy state. The percentage of molecules in the higher-energy state is_____ %.arrow_forward
