Propane (C3H8) is burned with 15% excess air. The conversion of the limiting reactant is 100%. The product streams contains 3 moles of CO₂ for each mole of CO. Propane and air are fed at 25°C at 1 atm. The product stream leaves at 800°C. Determine the amount of heat that must be removed per mole of propane fed (kJ/mole).

Potassium fluotitanate (K₂TiF₆), a starting material forproducing other titanium salts, is made by dissolvingtitanium(IV) oxide in concentrated HF, adding aqueous KF, andthen heating to dryness to drive off excess HF. The impure solidis recrystallized by dissolving in hot water and then cooling to 0°C, which leaves excess KF in solution. For the reaction of 5.00 g of TiO₂, 250. mL of hot water is used to recrystallize theproduct. How many grams of purified K₂TiF₆ are obtained?(Solubility of K₂TiF₆ in water at 0°C is 0.60 g/100)

Review | Constants | PeriIodic Table The standard heat of formation, Ar H°, is defined as the enthalpy change for the formation of one mole of substance from its constituent elements in their standard states. Thus, elements in their standard states have AfH® =0. Heat of formation values can be used to calculate the enthalpy change of any reaction. Part A For which of the following reactions is A,H° equal to Ar H° of the product(s)? Consider, for example, the reaction You do not need to look up any values to answer this question. 2NO(g) + O2(9) = 2NO2(9) Check all that apply. with heat of formation values given by the following table: • View Available Hint(s) Substance (kJ mol-1) NO(9) O C(s) + 02 (9)→CO2(9) 90.2 O2 (9) O Li(s) + F2(1)→LIF(s) NO2(9) 33.2 O Li(s) + F2(9)→LİF(s) O 2Li(s) +F2(9)→2LİF(s) Then the heat of formation for the overall reaction is A,H°= EnpAf H° (products)- nA¢H° (reactants) O CO(g) + ÷O2(9)→CO2(9) 2(33.2) [2(90.2) + 0] -114 kJ mol-1 O BaCO3(s)→BA0(s) + CO2(9)…

Liquid gas undergoes combustion in air, releasing 100kf of heat and producing two gaseous products. Include energy in the reaction. When HCL reacts with NaOH to produce NaCl and H2O, 60kj of heat is released in the surroundings. a. State whether the surrounding gets warmer or colder. b. Sketch a PE graph for this reaction.

Ammonia is oxidized in a continuous reactor 4NH3 g + 5O2 g --> 4NO g + 6H2O g delta AHr= -904.7KJ mol The feed stream (40 mole% NH3 and 60 mole% O2 )enters the reactor at 200 degrees celsius with 80% conversion of ammonia and the products leave at 300 degrees celsius. Determine the quantity of heat required to be added or removed from the reactor.

Use the chemical reaction below to answer the following questions HCI(aq) + NaOH(aq) → NaCl (aq) + H2O (I) AH298 = -58 kJ/mol (a) How much heat is produced when 200 mL of 0.3 M HCL (density = 1.00 g/mL) and 250 mL of 0.25 M NaOH (density = 1.00 g/mL) are mixed? (b) If both of the solutions at the same temperature and the heat capacity of the products are 5.39 J/g °C , how much will the temperature increase? (c) What assumptions are made when calculating your answers
