Stoichiometric amounts of C7H14 and oxygen are sealed in a flask that has a volume of 1.500 L. Pressure is measured and is 28.476861 atm at 297.15 K. The vapor pressure of the water is 0.02947 atm at 297.15 K. How many grams of each product are formed and with how many grams of C7H14 did you start with? R = 0.0820578(L)(ATM)/(K)(mol)
Each molecule can also be in one of two orientations. What is the entropy of this system of molecules in boxes with two possible orientations.
If a 10B nucleus absorbs a proton, the radioactive nuclide that is produced may undergo alpha decay. What nuclide is produced in the decay process?
Explain how the enthalpy, entropy, and free energy of this system change as the dissolving process proceeds. 2. Of the three parameters, AS, AH, and AG, specified in part 1, which has a sign diferent from the other two? Explain.
We find coesite and stishovite in shocked Coconino Sandstone at meteor Crater. We infer that coesite and stishovite formed from the transformation of quartz at high pressure and temperature.
Calculate the equilibrium concentration ratio of phosphocreatine to creatine in the following reaction if the concentrations of ATP and ADP are 8.0 mM and 1.6 mM, respectively.
which is commonly known as table sugar, reacts in dilute acid solutions to form two simpler sugars, glucose and fructose, both of which have the formula C6H12O6 At 23C
Its normal boiling point is 111.0oC and its molar heat of vaporization is 35.9 kJ/mol. What would be the vapor pressure (in torr) of toluene at 75.00oC?
Consider an area-source box model for air pollution above a peninsula of land. the length of the box is 15 km, its width is 80 km, and a radiation inversion restricts mixing to 15 m.
The electrons in the bonding orbital tend to be distributed between the two atoms. This is because of their tendency to be shared among the two nuclei.
The fluoridation of city water supplies has been practiced in the United States for several decades. It is done by continuously adding sodium fluoride to water as it comes from reservoir.
Predict whether the equilibrium favors the reactants or the products for each of the following reactions: a)H3PO4(aq)+H2O(l) H3O^+(aq)+H2PO4^-(aq). b)CO3^2-(aq)+H2O(l) OH^-(aq)+HCO3^-(aq) c)HS^-(aq)+H2O(l) H3O^+(aq)+S^2-(aq) d)HCN(aq)+CH3-NH2(aq..
