Hello!
In this case, according to the Avogadro's number, it is possible to compute the atoms of Kr in 2.00 moles as shown below:

Best regards!
Answer:false
Explanation:matter cannot be created or destroyed in a chemical reaction it is rearranged
You would need exactly 50 molecules of glucose.
<span>To solve this problem, You need to look up a picture/diagram of the electromagnetic spectrum. This will have the wave regions listed as well</span> as frequencies and wavelength.
Wavelength is distance/length of one wave, which can be calculated using frequency (hz = s^-1) and the speed of light.
2.998 x 10^8 m/s ÷ 3 x 10^19 s^-1 = 9.99 x 10^-12 m
The Frequency given falls in between X-rays and Gamma rays. The wavelength however; is in the Gama ray region.
