Consider the following balanced equation for the precipitation reaction that occurs in aqueous solution. Pb(NO3)2(aq)+2KI(aq)→PbI2(s)+2KNO3(aq) Answer the following questions if 0.50 L of 0.40 M Pb(NO3)2 is mixed with 0.50 L of 0.40 M KI: How many moles of PbI2 can form based upon complete reaction of Pb(NO3)2 and KI ? What mass of the precipitate (the solid product) should be expected to form in this reaction? (What is the theoretical yield of PbI2?)
To prevent tank rupture during deep-space travel, an engineering team is studying the effect of temperature on gases confined to small volumes. What is the pressure of 3.40 mol of gas D measured at 251 c in a 1.75-L container assuming ideal behavi..
We could find out more information about ths reaction by studying the temperature dependence of the rate constant, k. These same experiments could be carried out at a lower temperature (ice bath) and a second rate constant, k2 could be determined ..

A 300mL water sample has an initial pH of 10. 40mL of 0.02 N H2SO4 were required to titrate the water sample to pH 4.5. What is the total alkalinity of water in mg/L as CaCO3
If aluminum and sulfide come together to form an ionic compound, the formula for the ionic compound would be
If an aqueous solution containing Pb^2+ ions is electrolyzed using a current of 0.900 amps, calculate the mass of Pb(s) plated out after 50 minutes.
For the character table for C2v, why are the symmetry operations (sigmav xz and sigmav yz) different between the Z translation and the Rz rotation. Maybe a picture or drawing would help.
Compare the molar solubility of AgOH in pure water, with that in a solution buffered at pH 7.00. Note the difference between the two cases: when AgOH is dissolved in pure water, the pH does not remain at 7. The value of Ksp for AgOH is 1.5x10^-8 a..
