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.
B.)C=C is the right answer.
because h<span>aving more double bonds than single bonds decreases the melting point and, hence, the fluidity of the substance this is why butter is a solid but canola oil is a liquid at room temperature.</span>

Answer:
D
Explanation:
I believe the answer is D.
Answer:
1.25 mol
Explanation:
1 mol ---- 6.02*`0^23 atoms
7.50*10^23 atoms * 1 mol/6.02*10^23 atoms = 1.25 mol
