Question 6 Consider the integral $\int \cot(\theta) \cdot \ln(6 \sin(\theta)) \, d\theta$: This can be transformed into a basic integral by letting $u = $ and $du = \, d\theta$ After performing the substitution, you obtain the integral $\int \, du$
A student mixed 4.00 mL of 0.0120 M Pb(NO3)2 with 4.00 mL of 0.0300 M KI and 2.00 mL of 0.20 M KNO3 and observed formation of a yellow precipitate. F. How many moles of Pb^2+ remain in solution? G. What is the concentration of Pb^2+ in the equilibrium solution? (The volume of the equilibrium solution is still 10 mL.) H. Determine Ksp of PbI2 from this data. Show all work.
