20.00mL of a 1.100x 10^-4 mol/L Pb(NO3)2 is mixed with 80.00mL of 4.45010^-2 mol/L CaI2. Will a precipitate form? for the Ksp i got 2.7x10^-8 and im not sure if its right or not this is what i did [Pb2+] = (1.1x10^-4 mol/L x 0.02L)/(0.02L + 0.08L) = 2.2x1...

Tap water that contains Cl− at a concentration of 50 ppm is used to prepare a 0.100 mol/L AgNO3 solution. Does a precipitate form? How much? I don't know how to find out how much precipitate will form but a precipitate will form based on my calculations 5...

Magnesium metal reacts with hydrochlroic acid according to following reaction: Mg(s) + 2HCl(aq) -> MgCl2(aq) + H2 (g) over interval of 10.00s, the mass of Mg changes by -0.22g. What is the corresponding rate of consumption of HCl (in Mol/s) ? So what i th...

this is the rest of the calculations Q= 1.4x10^-4 ksp= 1.77x10^-10 Q>ksp so precipitation will form

Oh okay. thanks a lot :)

Seriously? People are just going to argue now instead of talk about this question... *sigh* I'll post you my results... 1. C 2. B,C 3. D 4. B 5. C 6. A 7. C (It is NOT cohesion, because cohesion is when two of the same particles stick. Adhesion, however,...

if anyone else is looking for this answer, 90.0 was correct. the other correct answer would be 68.0.
