A fossil fuel containing 84% C, 15% H and 1%S is burned with 20% excess air in a boiler. The stack gases are at 150 C. a) What is the concentration (ppm) of SO3 in the stack if equilibrium is established according to
the standard change in Gibbs free energy is ?G° = -32.8 kJ/mol. What is ?G for this reaction at 298 K when the partial pressures are P C2H6=0.100atm, P H2=0.100atm and P CH4=.750atm
Depict structural formulas that indicate the geometry of the following complexes. Define If the geometric or optical isomers are possible include them and label each form.
A gas cylinder containing 6.38 mol of neon has pressure of 491mmHg at 295k. If 3.22 mol helium is added at constant temp and pressure, what will be the pressure in the cylinder
Estimate Delta G or this reaction at each of the following temperatures. (Assume that Delta H and Delta S do not change too much within the given temperature range.)
Calculate the number of milliliters of stomach acid neutralized by 1 tablespoon of milk of magnesia (1 tablespoon = 3 teaspoons).
How can diacetylmorphine be ionised in the blood and what will the effects of this be on the molecule in circulation? (I assume that it will be more soluble?)
When photons with a wavelength of 310. nm strike a magnesium plate, the maximum velocity of the ejected electrons is 3.45 × 105 m/s.
22.5ml of .383 molar H2SO4 is required to completely neutralize 20ml of KOH solution. What is the molarity of the KOH solution?
Consider the combustion reaction between 30.0mL of liquid methanol ( density = 0.850 g/mL) and 15.0L of oxygen gas measured at STP. The products of the reaction are CO2 and H2O
The flask is then rinsed with 64.6 mL of distilled water and is then used to prepare a standard solution of KNO3. Compute the molar concentration of Cl- in the standard KNO3 solution if the flask is rinsed only one time with distilled water.
Calculate the change in temperature for 4.50 g of CaCl2 dissolved in 90.0 mL of H20. Assume that the calorimeter absorbs no heat (ie. Ccal=0)
