A E AA No Spacing Heading 2 I 6urpeaH Normal Text Box Shape Picture 31 6 E4. When glycerol (C3H5(OH)3) reacts with potas sium permanganate (KMnO4), a lot of heat can be released. The reaction can be used to start a fire when you go camping. The chemical equation between glycerol and potassium permanganate is given below. A JU student used solution calorimetry to determine the standard enthalpy of reaction During the experiment, 4.582 grams of KMnO4 was added to a 100.0 mL 0.040 M C3H5(OH)3 aqueous solution. The temperature increased from 21.0 C to 34.2 C. Assuming no heat loss during the experiment, that the density of the C3H5(OH), solution is 1.03 g/ml, and that the 0 specific heat of the solution is 4.184 J/g-K.

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) ▼
