(20 points) You are making some macaroni noodles on the stove from a box. The instructions say to boil 6 cups (1.40 L) of water before adding the noodles. The water temperature out of the tap starts at 20.0°C and the boiling temperature for water is 80°C. What is the heat needed, in kJ, to bring the water to boiling if we assume a boiling temperature of 100.°C, the density of water is 1.00 g/mL, and the specific heat of water is 4.18 J/(g °C)?

Level 2 – REDOX Titrations A student is in lab performing a REDOX titration on K3[Fe(C2O4)3]. 9.75 mL of 0.500 M KMnO4 were required to titrate a sample of K3[Fe(C2O4)3]. Unbalanced Chemical Equation:  C2O42- (aq) + MnO4- (aq) + H+ (aq) → Mn2+ (aq) + CO2 (g) + H2O (l) How many grams of C2O42- were in the sample?Select the closest answer.
