The coinage metals -- copper, silver, and gold -- crystallize in a cubic closest packed structure. Use the density of silver (10.5 g/cm3) and its molar mass (107.9 g/mol) to calculate an approximate atomic radius for silver
An organic material is extracted from water. The separatory funnel containins 10 mL of ether and 20 mL of water. Considering that the K (partition coefficient) value is 3.2,
The equilbrium constant for the decompositon at 25 degrees C is 2.3 X 10 ^ -4. At 25 degrees C , 7.5 g of NH4CO2NH2 is sealed in a 10 L flask and allowed to decompose.
analysis. To a 500 mL air sample at 700 torr and 38 deg C, she adds 20.00mL of 0.01017 M aqueous iodine which reacts as follows:
1. Gasoline (assumed to be 100% octane) is combusted in your car according to the following chemical reaction: 2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O

A shelf containing several chemicals (Salicylic acid, 4-(4-Hydroxyphenyl)butan-2-one {a.k.a. Raspberry Ketone} and 4-methylaniline) fell and the vials shattered.
Really confused on calculating/finding the half-equivalence point in a titration curve. This was a lab experiment done in my chem lab. We added 0.0750 M NaOH to acetic acid (pipet 10.00mL of ~0.1M HCH3CO2 into the beaker and add 40mL of DI water).
Hydrazine, ammonia, and hydrogen azide all contain only nitrogen and hydrogen. The mass of hydrogen that combines with 1.00g of nitrogen for each compound is .144, .216, and .240, respectively.
