Important information about Organic Oxygen Compounds
Can an ether molecule be made out of a methanol or ethanol molecule? Why or why not? What is the structure for 1-Octanol & Propane-1,2,3-triol? How would Ethanol, 1-Octanol, & Propane-1,2,3-triol compare in viscosity (ability to flow)? Why?
Do their size, shape, or molecular structure affect their physical consistency? Why?
How many grams of CaH2 are needed to generate 145 liters of H2 gas if the pressure of H2 is 825 torr at 21 C.
A 2.914-g sample gypsum, a hydrated salt of calcium sulfate, CaSO4, is heated at a temperature greater than 170 C in a crucible until a constant mass is reached.
What is the molecular formula of the molecule that had an empiricial formula of C2 H4 S and a molar mass of 180.35% g/molecular.
Calculate the pH of a solution that is .150 M in sodium formate and .200 M in formic acid (Ka=1.8*10^-4)
Photochemical chlorination of heptane gave a mixture of monochlorides containing 15% 1-chloroheptane. What other monochlorides are present? Estimate the percentage of each of these additioanl C7H15Cl isomers in a monochloride fraction.
If 158 of wet hydrogen is collected over water at 24 and a barometric pressure of 736 , how many grams of hydrogen have been consumed.
Two gas tanks are linked by a connecting tube of negligible volume with a valve. One contains 15 L of nitrogen at 7.2 atm of pressure. The other contains 8.3 L of helium at 4.1 atm of pressure.
When 0.062 moles of ammonium sulfate ((NH4)2SO4) are dissolved in enough water to make 200 milliliters of solution, how many ammonium ions are present.
