As I was reading special theory of relativity and general theory of relativity, I found out something very interesting which said that at the beginning of our universe, the universe was concentrated in a point called singularity where the laws of physics do not apply...
Now it has been proven that the universe is expanding... therefore giving support to the big bang theory...

Well in that point of space and time called singularity the laws of physics do not apply.. Then what made it burst into the huge big bang if there was nothing outside and in the inside the laws were not comprehensible then what made it burst into a huge explosion?... scientist say that only a supernatural power could have been the reason for such expansion... God? Think about it....

Sometimes science makes me reflex about my beliefs (religion) positively or negatively but this time is positively.

Ksp for Pb(OH)2=8*10^-16. In presence of excess hudroxide, the formation of a soluble hydroxo complex of lead(II) may be significant. The equilibrium reaction is
Pb+2(aq) + 3OH- (aq) <=> Pb(OH)3 (superscript -2)

Consider a saturated solution of lead(II) hudroxide at pH 12.0. Calculate the molar concentration of free lead(II) ion, Pb+2
