Various metals pack in cubic unit cells. The density of a metal and length of the unit cell can be used to find out the type for packing. For instance sodium has a density of 0.968 g/cm3 and a unit cell side length a of 4.29 Å. (1 Å = 1. 10-8 cm.)
(a) Define how many sodium atoms are in exactly 1 cm3?
(b) Define how many unit cells are in exactly 1 cm3?
(c) Define how many sodium atoms are there per unit cell?
(d) The atoms/unit cell suggests that sodium packs as a unit cell.

At high temperatures, a dynamic equilibrium exists b/w carbon-monoxide, carbon-dioxide, and solid carbon.
All organic (carbon-cointaining) products and cataloytic conditons must be shown as well as multiplel products. Studying for final. 2,4dimethypent-2- is the starting product
The precipitate is separated into two parts, which are then treated as follows: When cold 3M HNO3 is added to one part until the solution is acidic, the precipitate remains, even after heating to boiling. For each solid, indicate wheter these resu..
When compound Y is heated, it decomposes to the element X and hydrogen gas. Decomposition of 1g of Y yields 0.0250 mol of gas. Calculate the possible molar mass values for X.
