The third picture is the answer
Explanation:
there are 2 hydrogen atom 1 oxygen
Bicarbonate buffer system in blood consists of carbonic acid and bicarbonate ion. H2CO3/HCO3-
When a base enters the body the acid part of the buffer reacts with the base.
Thats the carbonic acid (H2CO3) reacts with the base.
Answer:
It is equal to Avogadro's number (NA), namely 6.022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.
Explanation:
The question is not very much clear.
If you are asking for molecules then 1 mole water= 6.023 * 10^23
If you are asking for atoms then 1 mole water= 6.023 * 10^23 * 3
If you are asking for particles then,
So, in your example you would have one mole of water molecules. If you dissociated those water molecules, than you would end up with 2 moles of hydrogen atoms, and one mole of oxygen atoms.
I hope that was helpful!
H=1 proton,1 electron
O=8 protons,8 neutrons and 8 electrons
total particles in one H2O molecule-28
total no. of particles in 1 mole of water- 6.023 * 10^23 * 28
A change of 1 Kelvin is exactly the same as a change of 1 degree Celsius.
