Naddik [55]
Catalyst has found usage in non-scientific terms as an almost metaphorical word for something provokes or speeds up action or change. The word's applicability to many topics made it easy for it to find its way out of the scientific lexicon and into other domains, in this case political. 

Its meaning is roughly the same, in that a catalyst in this context is something that facilitated or sped up the process of glasnost.

One distinct meaning that I notice is that "catalyst" in more casual or non-scientific speech is that it is often used as a creator of action all its own, an actor in itself, rather than a facilitating agent to a reaction, as its scientific definition states.

The Ksp of CaF2 is 4.0 x 10-11. What is the solubility of CaF2 in 0.10 M Ca(NO3)2? Give your answer using scientific notation an
Ilya [14]

Answer:

1.0\times 10^{-5} M is the solubility of CaF_2 in 0.10 M Ca(NO_3)_2.

Explanation:

Concentration of calcium nitrate = [Ca(NO_3)_2]=0.10 M

Ca(NO_3)_2\rightarrow Ca^{2+}+2NO_3^{-}

[Ca(NO_3)_2]=0.10 M=[Ca^{2+}]

Solubility product of the calcium fluoride = K_{sp}=4.0\times 10^{-11}

Solubility of calcium fluoride in calcium nitrate solution :

CaF_2\rightleftharpoons Ca^{2+}+2F^-

            (0.10+S)   (2S)

The expression of solubility is given by :

K_{sp}=[Ca^{2+}][F^-]^2

4.0\times 10^{-11}=(S+0.10)(2S)^2

Solving for S:

S=1.0\times 10^{-5} M

1.0\times 10^{-5} M is the solubility of CaF_2 in 0.10 M Ca(NO_3)_2.
