Discussion The purpose of the Density Lab was to determine the identity of four unknown solids and two unknown liquids by calculating their densities and comparing them to a density chart‚ taking into account error analysis and finally classifying the substances. In order to calculate this density‚ we first found the mass of the container that was to be holding the substances. We then found the volume of the substance‚ and lastly determined the mass of the container and substance. We subtracted

Chemistry Research Task The Periodic Table of Elements The Periodic Table of Elements is used as a way of displaying all the known chemical elements; it is accepted and used all over the world. The periodic table’s layout is very well structured; it consists of vertical rows called groups and horizontal rows called periods. It is one of the most important resources in chemistry and the key to discovering new elements. The beauty of the Periodic Table is that a lot of information about any
