Answer:
The correct answer is "They are both located in the nucleus".
Explanation:
I had to look for the problem and found that the particles are a Proton and a Neutron.
The atomic nucleus is the central section of an atom, is positively charged and has almost the entire mass of the atom.
The nucleus is formed by protons and neutrons, which are held together by strong nuclear interaction, which allows the nucleus to be stable.
Have a nice day!
Answer:
Initial rate of reaction is 
.
Explanation:
It is a second order reaction.
Initial rate of reaction = ![k[O_{3}]_{0}[NO]_{0}](https://tex.z-dn.net/?f=k%5BO_%7B3%7D%5D_%7B0%7D%5BNO%5D_%7B0%7D)
, where k is rate constant, ![[O_{3}]_{0}](https://tex.z-dn.net/?f=%5BO_%7B3%7D%5D_%7B0%7D)
is the initial concentration of 
and ![[NO]_{0}](https://tex.z-dn.net/?f=%5BNO%5D_%7B0%7D)
is the initial concentration of NO.
Here, k = 
, ![[O_{3}]_{0}=5.84\times 10^{-6}M](https://tex.z-dn.net/?f=%5BO_%7B3%7D%5D_%7B0%7D%3D5.84%5Ctimes%2010%5E%7B-6%7DM)
and ![[NO]_{0}=8.65\times 10^{-5}M](https://tex.z-dn.net/?f=%5BNO%5D_%7B0%7D%3D8.65%5Ctimes%2010%5E%7B-5%7DM)
So, initial rate of reaction = 
=
So, initial rate of reaction is
The answer is: D.unstable nuclei emitting high-energy particles as they formed more stable compositions.
Those high-energy particles are alpha particles
, beta particles
, gamma radiation.
For example, the decay chain of ²³⁸U is called the uranium series.
Decay start with U-238 and ends with Pb-206. There are several alpha and beta minus decays.
Antoine Henri Becquerel (1852 – 1908) was a French physicist and the first person to discover evidence of radioactivity.
Becquerel wrapped fluorescing crystal (uranium salt potassium uranyl sulfate) in a cloth, along with the photographic plate and a copper Maltese cross.
Several days later, he discovered that a image of the cross appeared on the plate.
The uranium salt was emitting radiation.
Because of this discovery, Becquerel won a Nobel Prize for Physics in 1903, which he shared with Marie Curie and Pierre Curie.
Answer:
0.533 mol O2
Explanation:
4 Fe3O4 + O2 -> 6 Fe2O3
1 mol O2 -> 6 mol Fe2O3
x -> 3.2 mol Fe2O3
x = (3.2 mol Fe2O3 * 1 mol O2)/ 6 mol Fe2O3
x= 0.533 mol O2
