Schrodinger and Heisenberg developed an alternate theory about atomic nature that contradicted some of Bohr's model of the atom.

How do changes resulting from new technology and evidence affect the reputation of the atomic theory?

Answer:

They don't affect the reputation of atomic theory at all.

Explanation:

Schrödinger and Heisenberg extended the model of the atom, as did Thompson, Rutherford, and Moseley before them.

Each model was based on the best available information at the time.

The availability of new information may require a new atomic model, but it doesn't destroy the reputation of older ones.

Answer: it did not affect the reputation of the atomic theory

Explanation:

Bohr only considered hydrogen and hydrogen-like atoms. Atoms with one electron. Schrödinger and Heisenberg extended it.

Every knowledge is science is alway built from previous knowledge. What you know to be right today might be proven wrong by someone else in the future. It doesn't mean you weren't right. So all scientists must keep an open mind, who knows, we might encounter aliens on earth in the future.

In IR spectroscopy, we normally talk about "frequencies" when in reality we are referring to wavenumbers. What is the mathematic
Svetach [21]

Answer:

Here's what I get.

Explanation:

(b) Wavenumber and wavelength

The wavenumber is the distance over which a cycle repeats, that is, it is the number of waves in a unit distance.

\bar \nu = \dfrac{1}{\lambda}

Thus, if λ = 3 µm,

\bar \nu = \dfrac{1}{3 \times 10^{-6} \text{ m}}= 3.3 \times 10^{5}\text{ m}^{-1} = \textbf{3300 cm}^{-1}

(a) Wavenumber and frequency

Since

λ = c/f and 1/λ = f/c

the relation between wavenumber and frequency is

\bar \nu = \mathbf{\dfrac{f}{c}}

Thus, if f = 90 THz

\bar \nu = \dfrac{90 \times 10^{12} \text{ s}^{-1}}{3 \times 10^{8} \text{ m$\cdot$ s}^{-1}}= 3 \times 10^{5} \text{ m}^{-1} = \textbf{3000 cm}^{-1}

(c) Units

(i) Frequency

The units are s⁻¹ or Hz.

(ii) Wavelength

The SI base unit is metres, but infrared wavelengths are usually measured in micrometres (roughly 2.5 µm to 20 µm).

(iii) Wavenumber

The SI base unit is m⁻¹, but infrared wavenumbers are usually measured in cm⁻¹ (roughly 4000 cm⁻¹ to 500 cm⁻¹).

The equation below represents a double replacement/displacement reaction;
Naddik [55]
AB+XY->AY+XB
We know that the answer would be KCl because of the switching that takes place during a double displacement reaction. Just like Zn and MnO4 switched and combined, the remaining elements, K and Cl, will combine.
We know that the answer is simply KCl because both K and Cl have an ion of only +/-1, meaning when they cross, no suffixes are made, since their ions are only 1.
For example, if you combined Mg with Cl, you would get MgCl2, because Mg has an ion of +2.
I hope this helps!

Which of these would be a good topic for a descriptive investigation? A. how the Moon's appearance changes B. what kind of dog f
katen-ka-za [31]

A. how the Moon's appearance changes

Explanation:

Descriptive investigation use very careful observations and measurements to develop findings.

Most geologists, meteorologists and astronomers use descriptive investigation to develop their findings.

  • Since most of their subject matter is inaccessible.
  • Descriptive investigation is used for indirectly making inquiries
  • It involves the development of an inquiry without formulating any hypothesis.

Write balanced chemical equation for the reactions used to prepare each of the following compounds from the given starting mater
creativ13 [48]

Explanation:

A balanced chemical equation is defined as the one that contains same number of atoms on both reactant and product side.

Whereas a chemical reaction that brings change in oxidation state of the reacting species is known as a redox reaction.

When there occurs decrease in oxidation number of an element then it shows the element has been reduced. And, if there occurs an increase in oxidation state of an element then it means the element has been oxidized.

(a)   The reaction between nitrogen and hydrogen to form ammonia will be as follows.

                N_{2} + 3H_{2} \rightarrow 2NH_{3}

So here, oxidation state of nitrogen is changing from 0 to -3. Whereas oxidation state of hydrogen is changing from 0 to +3.

Reaction between ammonia and nitric acid will be as follows.

            NH_{3} + HNO_{3} \rightarrow NH_{4}NO_{3}

Since, it is a combination reaction. Therefore, no change in oxidation state of reacting species is taking place.

(b)  Reaction for conversion of liquid bromine to hydrogen bromide is as follows.

            H_{2}(g) + Br_{2}(l) \rightarrow 2HBr(g)

Here, oxidation state of hydrogen is changing from 0 to +1. Therefore, oxidation of hydrogen is taking place. On the other hand, oxidation state of bromine is changing from zero to -1. Therefore, reduction of bromine is taking place.

(c)   Reaction between Zn and S will be as follows.

               Zn(s) + S(s) \rightarrow ZnS(s)    

Here, oxidation state of zinc is changing from 0 to +2. Hence, oxidation of zinc is taking place.

Oxidation state of sulfur is changing from 0 to -2. Therefore, reduction of sulfur is taking place.
