Using the technique of the previous problem ?E was found to be -2,000.00 kJ/mol of an unknown liquid hydrocarbon at 298 K. In another experiment it was determined that for each mole of hydrocarbon, 4 moles of oxygen gas are consumed and 9 moles of CO2 gas and 6 moles of H2O liquid are produced. Find ?H per mole of this hydrocarbon (in kJ) at 298 K.
Not used to answer question: This question is a bit awkward and unrealistic for molar amounts, but allows for random numbers. An example of a possible reaction is:C2H4(OH)2(l) +2.5O2(g) ?2CO2(g)+ 3H2O(l)
C2H4+2O2= 2CO+2H2O if 2.70 mol C2H4 is reacted with 6.30 mol O2 a. identify the limiting reagent b. calculate the moles of water produced
If the surface area of a human body is 16,100 square centimeters, what is the total weight of the atmosphere on a human body
Determine ?H for the formation of one mole of aluminium(III) oxide, Al2O3(s) from the elements?
Calcium phosphate, silicon dioxide, and coke may be heated together in an electric furnace to produce phosphorus, as shown in the following equation: 2Ca3(Po4)2+6SiO2+10C=6CaSiO3+10CO +P4
The reaction of 0.130 moles of a metal with an acidic aqueous solution in a calibrated calorimeter causes the temperature to increase by 49.0°C.
Calculate the mass of silver chloride required to plate 245 mg of pure silver. Silver chloride, often used in silver plating, contains 75.27% Ag
However, if you treat formaldehyde (CH2O) with potassium cyanide in water, you will not produce the cyanohydrin. You may even produce C3H6O3 (i.e., dihydroxyacetone and glyceraldehyde). Explain this either in words or reactions.
How many milliliters of 1.50 M H2SO4 are needed to neutralize 50.0 g of NaOH?
A solution of KOH in ethanol is made up by dissolving 0.335 g KOH in ethanol to form 250.0 mL of solution. Similarly, 1.455 g of C2H5I is dissolved in ethanol to form 250.0 mL of solution.
At 1000 deg. K, a sample of pure NO2 gas decomposes. 2NO2(g)f/r2NO(g) + O2(g) The equilibrium constant Kp is 158. analysis shows that the partial pressure of O2 is 0.14 atm at equilibrium.
For the reaction represented by the equation Cl2+2KCl+ Br2, how many grams of potassium chloride can be produced from 300. g each of chlorine and potassium bromide.
A metal is electrolyzed from aqueous solution by using an electrical current of 1.23 A for 2½ h, and 3.37 g of metal is deposited. In a separate experiment the number of electrons used for the reduction of the metal is 2.
