The K sp for barium fluoride, BaF2, is 2.45 × 10-5. What is the molar solubility of barium fluoride?

The molar solubility of barium fluoride is 0.0183 moles/liter.

Explanation:

The equation for the reaction will be as follows:

By Stoichiometry,

1 mole of gives 2 moles of and 1 mole of

Thus if solubility of is s moles/liter, solubility of  is s moles/liter and solubility of is 2s moles/liter

Therefore,  

Thus the molar solubility of barium fluoride is 0.0183 moles/liter.

yes, water is wet, just as it makes other things wet, it is wet itself, kinda like ice, when ice is in water, the ice makes water cold, and ice is cold, therefore with that example, water is wet

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
