Solid barium sulfate is placed into a beaker to form a saturated solution of barium sulfate. the solution has a barium concentration of 1x10-5m. what is ksp for barium sulfate?

Answer : The value of for barium sulfate is,

Solution :

The balanced equilibrium reaction will be,

The expression for solubility constant for this reaction will be,

Let the concentration of barium ion and sulfate ion be, 's'.

From the balanced equilibrium reaction, we conclude that the concentration of sulfate will be equal to the concentration of barium.

Now put all the value of in the above expression, we get the value of solubility constant for barium sulfate.

Therefore, the value of for barium sulfate is,

i think the answer is a, hope this is right, that would be my best guess.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
