Yes it is always changing, as time moves on new technological advancements are made. This makes it possible for new ideas to be created. For example the depiction of an atom went through many stages throughout the years in order to find out our current final version. New scientists and new ideas can add on to older ones, making explanations that make more scientific sense.
Molar solubility is the number of moles that are dissolved in 1 L solution.
when BaF₂ dissolves it dissociates into the following ions
BaF₂ --> Ba²⁺ + 2F⁻
if the molar solubility of BaF₂ is X, then molar solubility of Ba²⁺ is X and F⁻ is 2x
then the formula for the solubility product constant -ksp is;
ksp = [Ba²⁺][F⁻]²
ksp = X * (2X)²
ksp = 4X³
since ksp = 1.7 x 10⁻⁶
4X³ = 1.7 x 10⁻⁶
X = 0.0075 M
molar solubility of BaF₂ is 0.0075 M
Answer:
Liquids and gases show random movements because of potential and kinetic energy.
It happens when heat is applied to the particles and they gain more potential and kinetic energy and move around faster. With gases, they have the most energy.
