Propane, C3H8, is often used as a fuel for heating. It burns to produce carbon dioxide and water. Write a balanced equation for this combustion reaction. The heat of combustion for this reaction = 2044 kJ heat released per mole of propane burned. How many grams of oxygen would be required in the combustion of propane to produce 582 kJ of heat?
Mass of oxygen required = grams
When the equation above is balanced and all coefficients are reduced to their lowest whole-number terms, the coefficient for O2
Ethanol (C2H5OH) melts at -114 °C. The enthalpy of fusion is 5.02 kJ/mol. The specific heats of solid and liquid ethanol are 0.97 J/g-K and 2.3 J/g-K, respectively.
If 12.0 g of O2 is required to inflate a balloon to a certain size at 27 OC what mass of O2 is required to inflate it to the same size (and pressure) at 5.0 oC.
Draw the skeletal structure for major organic product produced when the arene given reacts with 2 equivalents each of Na and HOCH3.
Borane forms complexes with sulfides and amines. Draw a suitable structure to represent the complex formed between BH3 and dimethyl sulfide
