or no change. In the chemistry of nitrogen bacteria convert nitrogen
from the AIR, and hydrogen from cell into cell bound ammonia
N2 + 3 H2 -> 2 NH3
But where does that H2 come from? From metabolic reactions in the cell
that produce CO2 and H2O. The partial pressure from the gas CO2
molecule pretty much replaces the partial pressure of the N2, and any
real pressure difference would be made up of respiration of the H20 from
the cell into the air.

A) It becomes sand
I know this because Minecraft
The mole fraction of solute in a 3.87 m aqueous solution is 0.0697
<h3>
calculation</h3>
molality = moles of the solute/Kg of the solvent
3.87 m dissolve in 1 Kg of water= 1000g
find the moles of water= mass/molar mass
that is 1000 g/ 18 g/mol= 55.56 moles
mole of solute = 3.87 moles
mole fraction is = moles of solute/moles of solvent
that is 3.87/ 55.56 = 0.0697
A change that alters the identity of a substance resulting in a new substance or substances with different properties. A change to a substance that occurs without forming a new substance, such as a change in size or state of matter.
