The solubility of Cr(NO3)3⋅9H2O in water is 208 g per 100 g of water at 15 ∘C. A solution of Cr(NO3)3⋅9H2O in water at 35 ∘C is formed by dissolving 322 g in 100 g water. When this solution is slowly cooled to 15 ∘C, no precipitate forms.

The given question is incomplete. The complete question is as follows.

The solubility of in water is 208 g per 100 g of water at . A solution of in water at is formed by dissolving 322 g in 100 g water. When this solution is slowly cooled to , no precipitate forms. At equilibrium, what mass of crystals do you expect to form?

Explanation:

The given data is as follows.

 Solubility of in 100 g of water = 208 g (at )

 Amount of  in 100 g of water = 322 g (at )

At equilibrium, the mass of crystals formed is calculated as follows.

        Mass of crystal = Mass of  at - Mass of

Putting the given values into the above formula, mass of the crystals will be calculated as follows.

    Mass of crystal = Mass of  at - Mass of

                            = 322 g - 208 g

                            = 114 g

Thus, we can conclude that crystals formed is 114 g.    

beta decay is the answer

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
