The tetraethyl lead [Pb(C2H5)4] in a 25.00 mL sample of aviation gasoline was shaken with 15.00 mL of 0.02392 M 12. (Hint: one mole of 12 reacts with one mole of the tetraethyl lead). After the reaction was complete, the unused I2 was titrated with 8.14 mL of 0.02979 M thiosulfate solution. Calculate the weight in milligrams of [Pb(C2H5)4] (MW 323.4 g/mol) in each liter of gasoline. Submit Answer Tries 0/3 Post Discussion Send Feedbac

Primary reaction product

500.0 mL of 0.100 mol·L HCl(aq) was added to a high quality insulated calorimeter containing 500.0 mL of 0.100 mol·LNaOH(aq). Both solutions had a density of 1.000 g·mL and a specific heat of 4.184 J·g ·K . The calorimeter had a heatcapacity of 850.0 J·K . The temperature of the entire system rose from 25.50 C to 26.05 C.Calculate the heat of reaction.   Thank you!

Order these chemical species by increasing pH of an 0.1 M aqueous solution of each. That is, imagine making an 0.1 M solution of each species. Select1 next to the species that makes the solution with the lowest pH. Select 2 next to the species that makes the solution with the next higher pH, and so on. Notice that some of the rankings have been filled in for you already. Also notice that water is on the list. For that particular case, just compare the pH of pure water to the pH of the other solutions. Note for advanced students: for all charged species, you may assume the necessary counterions act as neither acids nor bases. relative pH of 0.1 M aqueous solution species H20 4 H,PO4 HNO, (Choose one) NO2 7 OH (Choose one) HF (Choose one) ▼
