It requires 799 kJ of energy to break one mole of carbon-oxygen double bonds in carbon dioxide. What
Interpretation:
The energy required to rupture one mole of
Concept introduction:
Bohr developed a rule for quantization of energy that could be applicable to the electron of an atom in motion. By using this he derived a formula for energy levels of electron in H-atom.
Relation between frequency and wavelength is,
C is the speed of light.
h is Planck’s constant (
E is energy of light particle.
The distance between any two similar points of a wave is called wavelength
Figure 1
Frequency is defined as number of wavelengths of a wave that can pass through a point in one second.
Answer to Problem 7.108QP
The wavelength of light used to break per bond is
Explanation of Solution
To calculate: The wavelength of light used to break per bond.
The energy of each photon is calculated as follows,
The wave length of light used to break per bond is
The obtained wavelength is in range of near UV region of electromagnetic spectrum which corresponds to lyman series of H-atom. The minimum energy required in this region for transition corresponds to
The obtained energy is more than required energy to break the
By using the formula for energy levels of electron in H-atom, the wavelength of light used to break per bond was calculated.

- When a tube containing hydrogen atoms is energized by passing several thousand volts of electricity into the tube, the hydrogen emits light than when passed through a prism, resolves into the "bright line" spectrum shown in Fig. 11.10. Why do hydrogen atoms emit bright lines of specific wavelengths rather than a continuous spectrum?arrow_forwardWhat major assumption (that was analogous to what had already been demonstrated for electromagnetic radiation) did de Broglie and Schrodinger make about the motion of tiny panicles?arrow_forwardCesium was discovered in natural mineral waters in 1860 by R. W. Bunsen and G. R. Kirchhoff, using the spectroscope they invented in 1859. The name came from the Latin caesius ("sky blue") because of the prominent blue line observed for this element at 455.5 nm. Calculate the frequency and energy of a photon of this light.arrow_forward
- Give a brief wave description of light. What are two characteristics of light waves?arrow_forwardOne bit of evidence that the quantum mechanical model is correct lies in the magnetic properties of matter. Atoms with unpaired electrons are attracted by magnetic fields and thus are said to exhibit pararamagnetism. The degree to which this effect is observed is directly related to the number of unpaired electrons present in the atom. Consider the ground-state electron configurations for Li, N, Ni, Te, Ba, and Hg. Which of these atoms would be expected to be paramagnetic, and how many unpaired electrons are present in each paramagnetic atom?arrow_forwardIn your own words, explain the photoelectric effect. How does the photon concept explain this effect?arrow_forward
- Heated lithium atoms emit photons of light with an energy of 2.9611019 J. Calculate the frequency and wavelength of one of these photons. What is the total energy in 1 mole of these photons? What is the color of the emitted light?arrow_forward6.17 The laser in most supermarket barcode scanners operates at a wavelength of 632.8 nm. What is the energy of a single photon emitted by such a laser? What is the energy of one mole of these photons?arrow_forwardOzone in the stratosphere absorbs ultraviolet light of wavelengths shorter than 320 nm, thus filtering out the most energetic radiation from sunlight. During this absorption, an ozone molecule absorbs a photon, which breaks an oxygen-oxygen bond, yielding an oxygen molecule and an oxygen atom: O3(g)+hvO2(g)+O(g) (Here, hv denotes a photon.) Suppose a flask of ozone is irradiated with a pulse of UV light of wavelength 275 nm. Assuming that each photon of this pulse that is absorbed breaks up one ozone molecule, calculate the energy absorbed per mole of O2 produced, giving the answer in kJ/mol.arrow_forward
