Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.

A 9.73 g sample of calcium sulfide was decomposed into its constituent elements, producing 5.41 g of calcium and 4.32 g of sulfur. Which of the statements are consistent with the law of constant composition (definite proportions)? << The mass percentage of calcium plus the mass percentage of sulfur in every sample of calcium sulfide equals 100%. The ratio of calcium to sulfur will vary based on how the sample was prepared. Every sample of calcium sulfide will have 5.41 g of calcium. The mass ratio of Ca to S in every sample of calcium sulfide is 1.25. Every sample of calcium sulfide will have 55.6% mass of calcium.
Write balanced chemical equations for each of the following descriptions of a chemical reaction. You do not need to include the phases of the reactants or products. IMPORTANT NOTE: Before attempting to balance the equations, you must first convert the compound names into the correct chemical formulas. If you begin to struggle with that, you may wish to go back to Chapter 4 and re-work naming problems. Calcium reacts with chlorine to produce calcium chloride. (Recall that chlorine is one of the diatomic molecules that are referred to by their element's name).
