Many thanks to you. My mathematical calculations were deprived of the derivative of atmospheric pressure.

I can ashore you steve that it is not possible. Sorry about your problem, no help here.

In a recent class of mine we went into a deep conversation about water.

We went into the breakup of water, its importance to organisms, etc... We

soon came to the issue of hard water, and how it can affect us. One

scholar recalled a documentary of heavy water. To this day I have not

found a reliable source to any valuable intel relating to this subject. Please

point me into a direction that my help me to find information regarding heavy

water.

Is this info more accurate?

21% Oxygen

79% Nitrogen

I think that there are worst possibilities that the rejection by the immunity system. what if this treatment was to do harm. Being able to perdict the outcomes of the experiment is key. what could go wrong? I think that in general the outcome is worse than the help it gives.

Just something to think about:-)

What is the differences between:

Elements

Compounds

Isotopes and

Radioisotopes?

I have found varying answers to this question and I need confirmation .

I searched what the two most abundent elements are in the atmosphere and hydrosphere.

For the atmosphere I found that 21% is Oxygen and 79 % Nitrogen.

For the hydrosphere I found thst the two most abundent elements are Hydrogen and oxygen. But I could not find percentages.

Please help me.
