Chemistry - Other explained in this solutionIf world energy consumption continues to rise at the present rate of 2.4%, how long will it take to double (expressed in years)?
Hint:Use first order kinetics.
Estimate dissociation energy of HF using simpe additivity rule If given that d(H-H) and D(F-F) IN H 2 is 336kj/mol and F2 is 258 kj/mol
Compute the amount of heat essential to fully sublime ninety grams of solid dry ice (CO 2 ) at its temperature of sublimation if it is given that the heat of sublimation for CO 2 = 32.3 kj/mol express your answers in kilojoules?
Calcium sulfide has a face-centered cubic unit cell with calcium ions in octahedral holes. If the radius of sulfide ion is 184pm and the density of CaS is 2.60 g/cm3.
What is the compounds molar mass if the density of a gaseous compound of phosphorous is 0.943g/L at 474K when its pressure is 728 torr.?
A steel tank has a volume of 438 L and is filled with 0.885 kg of oxygen. calculate the pressure of oxygen at 69.8 fahrenheit.
when a 50.0-g nugget of pure gold is heated from 35.0 C to 50.o C, it absorbed 5200.0J of energy. find the specific heat of gold.
Calculate the molar mass of the unknown gas. (remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0L
A chemist dissolves 0.9 g of an unknown monoprotic (one acidic H) acid in water. She finds that 14.6 mL of 0.426 M NaOH are required to neutralize the acid.
what will be the final temperature in degrees Celsius If the volume of a gas container at 32.0°C changes from 1550 mL to 755 mL,?
Determine the value of the equilibrium constant at this temperature - Ammonium Hydrosulfide NH4HS yields NH3(Ammonia) and Hydrogen sulfide
Calculate the molar concentration of OH- ions in a 7.5×10^-2 M solution of ethylamine C2H5NH2(Kb = 6.4x10^-4).
