What effect on the value of Ca(OH)2's Ksp (6.5x10^-6 ) would sucking up some suspended calcium hydroxide solid have? Would the Ksp value be higher or lower than the normal value? Why?
The Ksp of AgCl at 25 oC is 1.6 x 10-10. Consider a solution that is 1.0 x 10-4 M NaCl and 1.0 x 10-6 M AgNO3. 1. The solution is saturated.
heat is removed from 200.0 g of water with an initial temperature of 30.0°C? The specific heat of water is 4.184 J/gdeg.
A certain human gene was shown to have only 80% of its DNA sequence identical to that of an ape, but its corresponding protein sequence has 95% identity
Based on the value obtained in the three heating above, do you think the student should have confidence in his results? why? what do you think he should do to be more confident in his result
