Question 8 of 27 > The balanced reaction equation for combustion of heptane, CH 6, is CH6+110, — 700, +8H,0 If the reaction produced 40.5 g CO,, how many grams of heptane were burned? mass: g C,H, The reaction of limestone with hydrochloric acid is Caco, + 2HCI — CaCl, +CO, +H2O If the reaction produced 40.5 g CO,, how many grams of HCl reacted? mass: • HCI
5. Heptane is the zero of the octane rating of motor fuel. It burns according to the following: CH16+ 1102 à 7CO2 + 8H20 Estimate the enthalpy change in the reaction by using bond dissociation energies, and classify the reaction as exothermic or endothermic overall. (Average BDEs in kcal/mol: C-H, 99, 0-0, 119; C=0, 191; H-O 112]. (Hint: C-H16 has 16 C-H bonds) 6. Noting that all the reagents and products in problem 5 are gases under the conditions of...
Stream (1) at 29C containing equimolar ratio of pentane (CSH12) and heptane (CH16) and stream (2) of 1.5 mol/h flow rate at 42°C containing 80 mole% CSH12 and 20 mole% CH16 are mixed and heated to 302°C (stream 3, containing 45 mole% CH16 ) at constant pressure, as shown in Figure Quiz2 below, Using the specified assumptions and the enthalpies tabulated in the Table Quiz2 below, calculate the required heat for this method.
the heat combustion for n-heptane is 4,187kj/mol. how much heat is produced if 200kg of n-heptane C7H16) is completely combusted?
11. Kathleen burned heptane (C7H16) in the air: CH16 (1) + 1102(g) → 7CO2(g) + 8H2O(g). Which of the following is NOT correct for this reaction? a. 1 mol of C7H16 reacts with 11 mol of 02. b. C His is a liquid. c. CO is a gas. d. 1 mol of CyHo produces 7 mol of H2O. Answer:
Heptane has a boiling point of 98 °C; density 0.68 g/mL. It is used as a solvent for rubber cement. a) Draw the condensed structural, line angle formula and molecular formula of heptane. b) Is heptane a solid, liquid or gas at room temperature? c) Is heptane soluble in water? d) Will heptane float or sink in water? e) Write a balanced chemical equation for the complete combustion of heptane.
1) The heat of combustion for n−heptane, C7H16, is 4,817 kJ/mol. How much heat is released if 350 kg of this liquid burns completely? 2) The heat of combustion for ethane, C2H6, is 47.8 kJ/g. How much heat is produced if 7.0 moles of ethane undergo complete combustion?
Part II. Combustion 2. Pour by holding a burning splint over the heptane Use a test tube holder to invert a test tube over the flame produced by the bep- until it from the heptane flame. Quickly move the inverted test tube away from the flame and insert the burning splint into the inverted test tube. What happened to the burning splint? Carefully note ontop of itaud for couneseconds Hen test tube turtend e block colo up over tents. What...
The heat of combustion for n−heptane, C7H16, is 4,817 kJ/mol. How much heat is released if 850 kg of this liquid burns completely?
