The answer is four. The law of conservation of mass basically says that whatever is but in will always have the same mass coming out. so for example if you had 10 grams of water and then you heated it up, it is still 10 grams of water.
Explanation:
It is possible to predict a physical change or chemical change because they have very unique properties and differences.
A physical change is a change that alters the physical properties of matter especially form and state.
A chemical change is a change in which new kinds of matter is formed.
Here are some of the properties and indicators of the these change;
- A physical change is easily reversible
- Chemical changes are not easily reversible
- Physical changes leads to the production of no new kind of matter.
- Chemical change produces new kinds of matter
- Physical change involves no change in mass
- Chemical change involves a change in mass
- Physical change requires little to no amount of energy
- Chemical change requires considerable amount of energy.

Solubility product constants are values to describe the saturation of ionic compounds with low solubility. A saturated solution is when there is a dynamic equilibrium between the solute dissolved, the dissociated ions, the undissolved and the compound. It is calculated from the product of the ion concentration in the solution. For barium chromate, the dissociation would be as follows:
BaCrO4 = Ba^2+ + (CrO4)^2-
So, the expression for the solubility product would be:
Ksp = [Ba^2+] [(CrO4)^2-]
we let x = [BaCrO4] = [Ba2+] = [(CrO4)2-] = 2.81x10^-3 g/L ( 1 mol / 253.35 g ) = 1.11x10^-5
Ksp = x(x)
Ksp= x^2
Ksp = (1.11x10^-5)^2
Ksp = 1.23x10^-10
The Ksp of Barium chromate at that same temperature for the solubility would be 1.23x10^-10.
What is your question exactly?? lol sorry
