One way is for <span>a landowner to gather as much information as possible about his or her private water well, to know how it works, as well as who has had the land before them. The landowner needs to see if anyone has used pesticides in the area, as it can contaminate the well water. This is the most common way. The landowner can also check to see if any other chemicals have been spilt in the area or even a gas or oil leak, as that too can cause the contamination of well water.
I hope this helps.</span>
Nuclear reaction: ¹⁶O + p⁺ → ¹³N + α (alpha particle).<span>
Alpha decay is radioactive decay in
which an atomic nucleus emits
an alpha particle (helium nucleus)
and transforms into an atom with an atomic
number that is reduced by two and mass number that is reduced by four.
When oxygen-16 gain one proton, atomic mass is 17, but when lose alpha particle atomic mass reduces by four to 13.</span>
A sample of liquid benzene at 80°C and a sample of gaseous benzene at 80°C will have the same average kinetic energy of benzene molecules.
Let us recall that the average kinetic energy of molecules depends on the molar mass of the substance as well as the temperature of the substance. We have that;
average kinetic energy=
R = gas constant
NA =Number of molecules
M = Temperature in Kelvin
We can see that the average kinetic energy depends on temperature therefore, a sample of liquid benzene at 80°C and a sample of gaseous benzene at 80°C will have the same average kinetic energy of benzene molecules.

I would say A but I am not sure
