What is bayer strain theory?
Bayer's strain theory accounts for the strain in bonds within a ring compound. In a tetrahedral bond angle is 109.28 degrees. If none of the bonds are 3 in a ring chain isomer, then each angle will be of 60 degrees that is 109.28 degrees. That means there is a lot of strain. Strain order: 3>4>5~6>7>8>9
If HCL and Na2S2O3 are kept constant by how many degrees would this reaction have to be heated from 25 degrees C to precisely double the reaction rate?
Assuming the reaction is first order with respect to both HCl and Na2S2O3, increasing the temperature by 10 degrees Celsius will approximately double the reaction rate. So, you would need to heat the reaction from 25 degrees Celsius to 35 degrees Celsius to achieve this.
What are pseudo-first order reactions and do they differ from first order reactions?
Pseudo-first order reactions appear to be first order but depend on the concentration of a reactant that is present in excess, leading to a rate equation that behaves as first order. This can occur when the concentration of another reactant remains relatively constant throughout the reaction. This differs from first order reactions, where the rate is directly proportional to the concentration of a single reactant.
How hot to melt silver?
Silver has a melting point of 961.8 degrees Celsius (1763.2 degrees Fahrenheit). To melt silver, it needs to reach this temperature in order to transition from a solid to a liquid state.
How hot gold has to be to melt?
Gold has a melting point of 1,064 degrees Celsius (1,947 degrees Fahrenheit). This means that it needs to be heated to at least this temperature in order to melt and become a liquid.

What is the relationship between the diffraction angle and the wavelength of light in a diffraction grating experiment?
In a diffraction grating experiment, the relationship between the diffraction angle and the wavelength of light is described by the equation: d(sin) m. Here, d is the spacing between the slits on the grating, is the diffraction angle, m is the order of the diffraction peak, and is the wavelength of light. This equation shows that the diffraction angle is directly related to the wavelength of light, with a smaller wavelength resulting in a larger diffraction angle.
A laser beam of wavelength 630nm is directed normally at a diffraction grating with 300 lines per millimetre. Calculate the angle of diffraction of each of the first two orders.?
1/(3*10^5) = 0.000003(recurring) (630*10^-9)/0.000003(recurring) =0.189 sin^-1(0.189)=10.9 degrees (first order) 10.9*2=21.8 degrees (second order)
When X rays of wavelength 0.090 nm are diffracted by a metallic crystal the angle of first-order diffraction n 1 is measured to be 15.2 What is the distance between the layers of atoms responsi?
X-rays with wavelengths of 128 pm was used to study a crystal which produced a reflection of 15.8 degrees. Assuming first order diffraction (n = 1), what is the distance between the planes of atoms (d)
How do you calculate wavelength from diffraction grating?
You can calculate the wavelength of light using a diffraction grating by using the formula: λ = dsinθ/m, where λ is the wavelength of light, d is the spacing between the grating lines, θ is the angle of diffraction, and m is the order of the diffracted light. By measuring the angle of diffraction and knowing the grating spacing, you can determine the wavelength.
Is the first order spectra wider than the second order spectra in a diffraction grating experiment?
Yes, the first order spectra is typically wider than the second order spectra in a diffraction grating experiment because the diffraction angle for higher orders (such as second order) is smaller, resulting in a narrower spread of the spectral lines.
To find wavelength of spectral line using diffraction grating?
To find the wavelength of a spectral line using a diffraction grating, you can use the formula: dsin(θ) = mλ, where d is the spacing of the grating lines, θ is the angle of diffraction, m is the order of the spectral line, and λ is the wavelength of the light. By measuring the angle of diffraction of the spectral line and knowing the grating spacing, you can calculate the wavelength of the light.
A crystal has an interplanar spacing of 98.2 pm. Using first order diffraction, what is the X-ray wavelength required to produce a reflection with an angle of 17.5 degrees?
Using d sin 𝜃 = n𝜆, d=98.2pm, n=1, 𝜃=17.5º 98.2sin(17.5º) = 1𝜆 𝜆=29.53pm
How can the interplanar spacing calculation be performed for a crystal lattice structure?
To calculate interplanar spacing in a crystal lattice structure, you can use Bragg's Law, which relates the angle of diffraction to the spacing between crystal planes. This formula is given by: n 2d sin(), where n is the order of the diffraction peak, is the wavelength of the X-ray used, d is the interplanar spacing, and is the angle of diffraction. By rearranging this formula, you can solve for the interplanar spacing (d) by measuring the angle of diffraction and the wavelength of the X-ray.
Will the angular separation between red blue rays be greater in first or in second order?
The angular separation between red and blue rays will be greater in the first order compared to the second order. This is because diffraction angles increase with higher orders of diffraction.
In order for a triangle to be a right angle what do you do?
One of the angles has to be 90 degrees.
Is a right angle and an obtuse angle always supplementary?
No. In fact, they never are. A right angle by definition is 90 degrees. An obtuse angle is any degree greater than 90. In order for two angles to be supplementary, they must equal 180 degrees. Because an obtuse angle is always greater than 90 degrees, and a right angle is always 90 degrees, an obtuse angle and a right angle can never be supplementary.
