what mass of octane in grams is required to produce 7260 kJ of heat?
What mass of butane in grams is necessary to produce 1.5 times 10^8 kJ of heat? What mass of CO_2 is produced? Assume the reaction to be as follows: C_4 H_10 (g) + O_2(g) rightarrow 4CO_2(g) + 5H_2 O(g), delta H = -2658 kJ
If a gallon of gasoline is approximately 3200 grams and roughly 85% Octane (C8H18) by mass - solve for the heat energy produced (in kj), grams of CO2 and grams H2O from combustion of 1 gallon of gasoline
Find the mass of ethane C2H6 required to produce 5000 kJ of heat. C2H6(g) + 7 2O2(g) = 2CO2(g) + 3H2O(g), ∆H◦ = −1423 kJ/mol. (C2H6) = 30.07 g/mol.
Calculate the heat (in kJ) required to completely vaporize 11.42 g of n-octane, C8H18, if the sample is initially at –20 ºC. Pertinent data are: m.p. = -57 ºC, b.p. = 126 ºC, ΔHfus = 20.65 kJ/mol, ΔHvap = 38.6 kJ/mol, Cp(liq.) = 254 J/K-mol.
The heat of combustion of octane is -5430 kJ/mol. 1.000 g sample of octane (C8H18) is burned in a bomb calorimeter at an initial temperature of 25.00ºC. The heat capacity of the calorimeter (also known as the “calorimeter constant”) is 837 J/ºC. Calculate E for the combustion of octane. (You will need a balanced chemical equation to find H) What is the final temperature of the calorimeter?
What mass of carbon monoxide must be burned to produce 175 kJ of heat under standard state conditions?
Calculate the minimum amount (in grams) of O2 needed to produce 243.2 kJ of heat, when it is reacted with Al(s) to form Al2O3(s) at 25°C and 1 atm. Delta Δ Hf Al2O3(s) = − 1676 kJ/mol
Octane (C8H18) is a component of gasoline that burns according to the following equation: C8H18(l)+252O2(g)→8CO2(g)+9H2O(g) ΔH∘rxn=−5074.1kJ What mass of octane (in g ) is required to produce 1850 kJ of heat?
of water fusion How much heat in kJ would be required to convert 31.6 grams of ice from -10.0°C to liquid water at 0.00*C. The AH, is 6.02 kJ/mole, the specific heat of ice is 2.01 Jg*c", and the specific heat of liquid water is 4.18 jgc". Report your answer to 1 decimal place.
The enthalpy of fusion of H2O (s) (ice) if heat fusion= 6.01 kj mol-1. What mass (ink) of ice can be melted with the heat released from the combustion of 1.00 gallon of octane? ( The temperature of the ice and resulting water remains constant at 0 degrees C through the melting process.) Please show work
