Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 12.0 torr at 35 degrees C. the vapor pressure of pure ethanol at 35 degrees C is 1.00 x 10^2 torr.
Consider the oxidation of sodium metal to sodium oxide described by the balanced equation
Stalactites--the long icicle, icicle like formations that hang from the ceilings of caves--are formed from recrystallizing minerals like calcite (calcium carbonate, CaCO3, 100.09 g/mol). The Ksp of calcium carbonate is 4.5 x 10^-9.

What is the molar concentration of methanol in the mixture? Give answer in M, 2 significant digits, do not write down the units.
By requiring to evaluate the integral (Use 100,000 m/s for an upper limit on velocity), determine the percentage of hydrogen atoms that have speed greater than the escape velocity which the maximum season temperature of Mars is 293 K.
what volume of methane, measured at STP, must be burned? (ΔH°combustion for CH4 = -891 kJ/mol)
What effect on the boiling point of a liquid is produced by: a) The presence of a soluble non-volatile impurity?
What is the C2O42- concentration in a solution that is 0.10 M in oxalic acid and 1.0 M in HCl? (Consider that the oxalic acid concentration at equilibrium for this common ion problem is 0.10 M.)
A 40 foot fiberglass boat hull weighs 2000 kg. 60% of that is a fully cured crosslinked polyester resin (the remainder is the glass reinforcing fibers, pigment, fillers, etc.).
