Answer is: concentration ammonia is higher than concentration of ammonium ion.
Chemical reaction of ammonia in water: NH₃ + H₂O → NH₄⁺ + OH⁻.
Kb(NH₃) = 1,8·10⁻⁵.
c₀(NH₃) = 0,8 mol/L.
c(NH₄⁺) = c(OH⁻) = x.
c(NH₃) = 0,8 mol/L - x.
Kb = c(NH₄⁺) · c(OH⁻) / c(NH₃).
0,000018 = x² / 0,8 mol/L - x.
solve quadratic equation: x = c(NH₄⁺) = 3,79·10⁻³ mol/L.
1860-х годах, а кульминацией — распространение поточного производства и поточных линий. В 1860—1870-х годах технологическая революция быстро охватила Западную Европу, США, Российскую империю и Японию.
Which property of gas affects the gas by change in that property ?
Explanation:
It shows , Hydrogen bonding , Since ,
The molecule of water have a strong electronegative atom of oxygen and a hydrogen atom ,
So , the electronegative oxygen atom can interact with the other hydrogen atom of the other water molecule .
The molecule of Carbon tetrabromide have polar bonds of carbon and bromine atom , but overall the molecule is non - polar in nature , due to its tetraderal structure , hence ,
the molecule shows only dispersion forces .
The molecule of dichloromethane has Dipole Dipole forces due to difference in electronegativity between atoms .
