Why resolution power in TEM microscope is higher than SEM microscope
sleet_krkn [62]

Answer:

Here's what I get.

Explanation:

Two factors:

1. Higher accelerating voltages

Both types use a beam of accelerated electrons as a source of illumination.

Resolution depends on the wavelength of the electron beam. The shorter the wavelength, the smaller the objects you can "see."

SEMs usually use acceleration voltages up to 30 kV, while TEMs can set them as high 300 kV. Thus, the electron wavelengths in TEMs are shorter by a factor of 10.

2. Less spherical aberration

Spherical aberration degrades the quality of the image. It decreases as wavelength decreases, so you can push the magnification higher with a TEM without losing image quality.

Which bond is best described as an intermolecular attraction due to partial charges formed in polar covalent bonds?
Kay [80]

It is the bond in hydrogen.

Reason: The attraction between hydrogen and the electronegative atoms form the polar covalent bond. This bond can result in partial charges and attraction of molecules with opposite partial charges.

WILL GIVE BRAINLIEST AND 5 STARS what is the purpose/ use of a Bunsen Burner
Roman55 [17]

A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion. The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both. Have A Great Day :)

Answer: The pressure will be 411 GH.

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant volume

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2}

where,

P_1\text{ and }T_1 are the initial pressure and temperature of the gas.

P_2\text{ and }T_2 are the final pressure and temperature of the gas.

We are given:

P_1=570\\T_1=2.33\\P_2=?\\T_2=1.68

Putting values in above equation, we get:

\frac{570}{2.33}=\frac{P_2}{1.68}\\\\P_2=411

Thus the pressure will be 411 GH.
