What is the working of NMR?

Chemistry
1 answer:
tiny-mole [99]3 years ago
4 0

Answer:

NMR stands for Nuclear Magnetic Resonance, and NMR spectroscopy is the technology that makes use of the phenomena of NMR in the analysis of a material's molecular structure through measurement and observance of the nuclear spin interactions, in order to determine the biological, physical and chemical properties of the material

NMR works by the noting that some atoms in molecules placed in a strong magnetic field display the characteristics of small magnets. The application of a broad spectrum radio frequency to the molecules will cause the nuclei to resonate at particular frequencies. An NMR spectrum is formed from the measured nuclei resonant frequencies such that the graph peaks shows the correct frequencies in the sample and the peak height is directly related to the proportion or number of the nuclei which are resonating to a given frequency, such that the frequency values are indicative of the type of atoms and their distances apart from a given atom

Explain the different results of stress on layers of rock. Include a discussion of whether each result happens slowly or quickly
Alex_Xolod [135]
There are three specific types of stress.
Compression occurs when pressure pushes in on an object from opposite sides this happens slowly.
Tension occurs when pressure pulls on opposite sides of an object, causing it to stretch this happens quickly.
shear occurs when two objects try to slide past each other in opposite directions this happens not to fast but not to slow.

Which metal reacts with concentrated naoh to produce hydrogen gas?
MArishka [77]
The metal which react with concentrated sodium hydroxide to produce hydrogen gas is ALUMINIUM. 
The equation of the reaction is as follows:
2AL + 2NaOH + 2H2O = 2 NaALO2 + 3H.
The product formed is called sodium aluminate. The reaction is an exothermic reaction and is accompany by the evolution of hydrogen gas.

A gas of unknown molecular mass was allowed to effuse through a small opening under constant-pressure conditions. It required 10
masya89 [10]

<u>Answer:</u> The molar mass of unknown gas is 367.12 g/mol

<u>Explanation:</u>

Rate of a gas is defined as the amount of gas displaced in a given amount of time.

\text{Rate}=\frac{V}{t}

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

\text{Rate of effusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}

So,

\left(\frac{\frac{V_{X}}{t_{X}}}{\frac{V_{O_2}}{t_{O_2}}}\right)=\sqrt{\frac{M_{O_2}}{M_{X}}}

We are given:

Volume of unknown gas (X) = 1.0 L

Volume of oxygen gas = 1.0 L

Time taken by unknown gas (X) = 105 seconds

Time taken by oxygen gas = 31 seconds

Molar mass of oxygen gas = 32 g/mol

Molar mass of unknown gas (X) = ? g/mol

Putting values in above equation, we get:

\left(\frac{\frac{1.0}{105}}{\frac{1.0}{31}}\right)=\sqrt{\frac{32}{M_X}}\\\\M_X=367.12g/mol

Hence, the molar mass of unknown gas is 367.12 g/mol
