Calculate the mass deficiency in amu, binding enery in J/atom, and binding energy in MeV/nucleon for zinc-64, with an actual mass of 63.9291 amu.
When 50.0 mL of water containing 0.50 mol HCl at 22.5°C is mixed with 50.0mL of water containing 0.50 mol NaOH at 22.5°C in a calorimeter, the temperature of the solution increases.
the hypothetical metal Q with atomic mass of 68.33 has two isotopes ^67Q (isotopic mass 66.945 amu) and ^69Q (isotpes mass 68.958 amu) calculate the abundance of ^67Q in %
How do the enthalpy of dissolution, the crystal lattice energy, and the solvation energy of the two salts relate to these experimental observations?
A set of two gas bulbs, with volumes of 500 mL and 300 mL, are connected by a closed stopcock. The 500 mL bulb contains 450 torr of Ne gas, and the 300 mL bulb contains 150 torr of Cl2 gas
Using curved arrows to symbolize electrons, write a complete reaction mechanism for the bromination of acetanilide to create p-bromoacetanilide.
Using the procedure in the lab manual for the synthesis of aspirin (MM = 180.154 g/mol), you recover 1.34 of aspirin. Calculate your percent yield of aspirin.
How much heat is absorbed when 28.3g H2O(s) at 0 degrees celcuis is converted to liquid at 0 degrees celcius
From a purely statistical standpoint -considering only the number of hydrogens on a particular carbon that could be lost from the intermediate carbocation
When a solution of hydrogen peroxide (H2O2) is put on a cut, it bubbles, producing water and oxygen gas. If someone puts 0.54 mL of a 3.00% hydrogen peroxide solution on a cut, what is the volume in mL of oxygen produced?
Suppose that coal of density 1.5 g/cm3 is pure carbon. (It is, in fact, much more com- plicated, but this is a reasonable ?rst ap proximation.)
The percentage of an additive in gasoline was measured six times with the following results: 0.14, 0.15, 0.16, 0.17, 0.20, 0.11%. Find the average and RSD and 90% confidence intervals for the percentage of the additive.
