Sn + 2I2 ---> SnI4 (Ac2O,AcOH,reflux on arrow) SnI4 + 2PPh3 ---->(PPh3)2SnI4 (CHCl3 on arrow) SnI4 + (Me2SO)2 ----> SnI4(Me2SO)2 (CH2Cl2 on arrow) Need mechanisms for these reactions if there is any.

Decrease in stability of stannic halides by complexing with phosphines and sulfoxides

Why are stannic halides rendered more inert (towards hydrolysis) by complexing with phosphines and sulfoxides?

Citric Acid

Citric acid is concentrated in citrus fruits and plays a central matabolic role in nearly every animal and plant cell. How many moles of citric acid are in 1.90 qts of lemon juice *d=1.09 g/ml* that is 6.62% citric acid by mass? *Ive tried this problem 4 times and cant figure out the answer...Please post the stoich... setup as well as correct answer. Problem 2: Nitrogen *N*, phosphorus *P*and potassium *K* are the main nutrients in plant fertilizers. According to an industry convention, the numbers on the label refers to the mass percfents of N, P2O5, and K20, in that order. Calculate the N:P:K ratio of a 15:2:1.0 x10^1 fertilizer in terms of moles of each elemnt, and expres... click for more
