Your answer is Answer thank me later :) <3
Explanation:
Hello!
the atomic difference between uranium-235 and uranium-238 is that <span>uranium-235 has three fewer neutrons than uranium-238
Isotopes are atoms of the same elements which are only different in their amount of neutrons. That difference in the number of neutrons gives them different masses. Some isotopes are unstable, and they release neutrons (radiation) to transform into other, more stable, isotopes. When this happens the isotope is called a "radioactive isotope".

<span>c = speed of light = 3.00 x 10^5 km/s = 3.00 x 10^8 m/s
λ = wavelength of the microwave radiation = 3.50 cm = 0.035 m
f = frequency (in Hertz) = to be determined
f = c/λ = 3.00 x 10^8 m/s / 0.035 m
f = 8.57 x 10^9 Hz Frequency</span>
According to the law of conservation of matter, the number of Atoms<span> is not changed by a chemical reaction.

They're the same before and after a chemical reaction</span>
<u>The given reaction is:</u>
F2 + ClO2 → 2FClO2
Rate = k[F2][ClO2]
<u>Explanation:</u>
The possible mechanism for this reaction can be broken down into two steps with the slow step being the rate determining step
Step 1: F2 + ClO2 → FClO2 + F ----------- Slow
Step 2: F + ClO2 → FClO2 ----------- Fast
-----------------------------------------------------------
Overall: F2 + 2ClO2 → 2FClO2
Rate = k[F2][ClO2]
