Answer: 7 milimoles of dissolve in 1 litre water.
Explanation:
Given: gas is passed through water at 293K.
Assumption : exerts a partial pressure of 0.987 bar.
Take : Henry's constant = 76.8 Kbar
To find : Number of moles of gas dissolve in 1 litre water.
According to Henry's law,
moles in 1 liter of water =
Let n= moles of nitrogen
Total moles = 55.56+n
So,
Hence, 7 milimoles of dissolve in 1 litre water.
It will form a Nitrate ion NO3-
In comparing two isotopes of the same element, the atomic number, stays the same.
Allow me to explain: The protons in an isotope ALWAYS stays the same, but the neutrons change. But, what's the atomic number made up of?
Protons, which means it won't change.
However, the atomic mass is made up of neutrons + protons, so only the atomic mass would change - not the atomic number.
Average rate of reaction of H2 over this time is calculated as
initial concentration of H2 minus final concentration of H2
That is
{(0.35mol/l -0.12mol/l) / 50 sec}= 4.6 x 10 ^-3 mol/l/sec
