how many grams of baf2 are dissolved in 75.0 ml of a saturated solution of baf2? ksp = 1.00 x 10-6
Using the solubility product of the saturated solution, the mass of BaF2 dissolved is 0.083 g.
The equation of the reaction is obtained from;
BaF2(s) ⇄ Ba^+(aq) + F^-(aq)
The concentration of the substance can be obtained from the Ksp as follows;
Ksp = [Ba^2+] [2F^-]^2
Ksp = 4x^3
x = ∛Ksp/4
x = ∛ 1.00 x 10-6/4
x = 6.3 x 10^-3 M
Given that;
mass/molar mass = concentration x volume
molar mass = 175 g/mol
concentration = 6.3 x 10^-3 M
volume = 75.0 ml or 0.075 L
Mass = ?
Mass = concentration x volume x molar mass
Mass = 6.3 x 10^-3 M x 0.075 L x 175 g/mol
Mass = 0.083 g

Jane made this picture to represent a chemical reaction:
Two circles, one white and the other gray are shown on the left. A small portion of the two circles overlap and the label below the circles is XY. An arrow pointing right is shown on the right of the overlapping circles. There are two circles on the right of the arrow, one white and the other gray, and there is a plus sign between them. The white circle is labeled X and the gray circle is labeled Y.
Which of the following statements best explains the type of chemical reaction represented by Jane's picture? (5 points)
It represents a synthesis reaction because one combined reactant forms multiple products.
It represents a synthesis reaction because the same atoms are present in the reactants and products.
It represents a decomposition reaction because one reactant breaks apart and forms two products.
It represents a decomposition reaction because the total mass of the products is less than the mass of the reactant.
The reaction represents a decomposition reaction because XY is broken into its constituents.
A decomposition reaction is one in which the reactant is broken up into its constituents. In this case, the reactant is XY. The reactant is shown in the left hand side. The reactant is broken up to yield the products. X and Y.
Since the reactant was broken up into the one white and one gray circles labelled X and Y, then the reaction is a decomposition reaction.

Which of the following liquids has the highest viscosity
A water
B oil
C milk
D honey
Answer:
honey has the highest viscosity
According to the given option, honey is the liquid that has the highest viscosity. So, the correct option is D.
What do you mean by Viscosity?Viscosity may be defined as the effects of a liquid by probity of which an internal resistance comes into play when the liquid is in movement and resists the comparable motion between its distinct layers.
Among all the given options, honey possesses more strong intermolecular attractive forces that result in the high compaction of particles in the honey.
After honey, Oil is more viscous followed by milk, and then water.
Therefore, the correct option for this question is D.

Why do some atoms form chemical bonds while others do not?
Answer:
Atoms of these elements have full outer electron shells. These atoms are stable and very rarely form bonds with other atoms. If the electronegativity values between two atoms are comparable, they may still form chemical bonds to increase the stability of their valence electron shell
