We put 5 mL of 0.1 M lead nitrate solution in a test tube , then 5 mL of 0.1 M sodium oxalate , sheked and mixed , (i observed larg amount of percipitate in the test tube and the clear solution is very little), we late the percipitate settle and we decanted the liquid above it . finally we added 5 mL of dilute nitric acid and strred with a rode, I obseved the opposit thing , the percipitate was very small amount but the clear solution is larg amount.
What formula of the percipitate formed? and what do you observe upon the addition of dilute HNO3? and what equillibrium has been disturbed? would you expect lead chloride to dissolve in dilute HNO3? Explain
If a second experiment is done with half as much H2O2 as the experiment in question 1, and the solution turns blue in 180 seconds, what is the order of the reaction with respect to H2O2?

A stock solution was prepared by dissolving exactly 0.4000 g of pure ASA (180.16 g/mol) in 10.00 mL of NaOH and heating the solution to a gentle boil.
Really struggling with this one dy/dt = 2t(y + 1) + 2at^3 where a is a parameter. Find the general solution of the ODE when a = 0 using the fact that it is separable. After this, use the fact that that it is a linear ODE to find an integrating fac..
