Answer:
potassium bromide can only conduct electricity when in an aqueous solution due to the electrostatic force between the ionic bonds
ALL organic molecules have carbon.
Hope this helps :)
Answer:
In chemistry, a group is a vertical column in the periodic table of the chemical elements. ... Each element within a group has similar physical or chemical properties because of its atom's outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
Answer is: pOH = 3,29.
Kb(NH₃) = 1,5·10⁻⁶.
c(NH₃) = 0,175M.
pOH = ?
Chemical reaction: NH₃ + H₂O ⇄ NH₄⁺ + OH⁻.
Kb = c(NH₄⁺) · c(OH⁻) ÷ c(NH₃).
c(NH₄⁺) = c(OH⁻) = x.
x² = Kb · c(NH₃)
x² = 1,5·10⁻⁶ · 0,175 = 2,625 ·10⁻⁷.
x = c(OH⁻) = √2,625 ·10⁻⁷ = 5,12 · 10⁻⁴.
pOH = -log(c(OH⁻)) = 3,29.
Explanation:
The problem deals with a phase transition from solid to liquid. To the left we have ice and to the right we have liquid water.
For such change to take place, the process of melting must occur. During melting, a solid changes state from solid to liquid by taking energy from the environment.
- In solid state, the molecules of the water are in a fixed state about their fixed lattice.
- As the solid ice gains energy from the environment, it begins to melt.
- Energy increase causes the molecules of the water to start flowing to form a liquid.
