How could you ascertain wheter the alcohol or the carboxylic acid furnishes the hydroxyl group that appears in the molecule of water produced in formation of an ester
Calculate the percent of volume that is actually occupied by spheres in a face-centered cubic lattice of identical spheres. You can do this by first relating the radius of a sphere,r
Gas cylinder A has a volume of 48.2 L and contains N2(g) at 8.35 atm at 25 ºC. Gas cylinder B, of unknown volume, contains He(g) at 9.50 atm at 25 ºC
What do you expect will happen to the position of this equilibrium when the total pressure of the gases in the reaction mixture is doubled by injecting some argon (Ar) while maintaining the temperature constant.
if 0.100 m NaCl is added slowly to a beaker containing both .120m AgNO3 and .150m Pb(NO3)2 at 25 celsius which will precipitate first AgCl or PbCl2?
if 19.65mL of .145M nitric acid is required ti neutralize 50.0mL of barium hydroxide what is the molar concentration of the base? 2HNO3+Ba(OH)2-->Ba(NO3)2+2H2O
what volume of .2500M colbaat(III)sulfate is required to react completely with 5.00 grams of sodium carbonate?
We place 1.32 mol PCl5 in a 1.0 L flask and allow it to reach equilibrium at a given temperature. What is the final concentration of Cl2 in the flask?
The solute increases the volume of the solution, and an increase in volume requires an increase in the temperature to reach the boiling point (derived from PV = nRT).
Aromatic Compounds :sample question, Both naphthalene and azulene have 10 pie electrons and are aromatic. Pentalene is apparently antiaromatic and is unstable even at -100 degrees C.
A moth-ball, composed of naphthalene (C10H8), has a mass of 1.32 g. How many naphthalene molecules does it contain?
A 10.4-g sample of CaCl2 is dissolved in 107 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C ..
A nonelectrolyte solution adsorbs on an electrically neutral solid through a liquid. Two surfaces of this type are brought close to one another in the liquid such that they interact.
