Take note of any specific safety guidelines or reminders for a given lab activity or assignment. If you are unsure of the procedure after reading the protocol, contact the instructor for clarity before starting. Select a safe site for lab activities in your home. The kitchen is recommended, but any place that is well ventilated, has a flat and stable working surface, has access to water, and can be cleaned easily in the case of spills is recommended. Keep laboratory materials safely away from children and pets. If possible, keep all unauthorized people out of your selected site when chemicals are in use in order to avoid any unforeseen accidents. If anyone is allowed to observe you or participate in experiments, follow all of the proper safety rules. Do not eat, drink, or prepare food while conducting the lab experiment. Never place any instruments or materials in your mouth.

Periodic Table Virtual Lab Answer Key | medicoguia.com
Figure 1. Chromium compounds are widely used in industry, such as for chrome plating, in dye-making, as preservatives, and to prevent corrosion in cooling tower water, as occurred near Hinckley. Cr III , an ingredient of many vitamin and nutritional supplements, forms compounds that are not very soluble in water, and it has low toxicity. But Cr VI is much more toxic and forms compounds that are reasonably soluble in water. Exposure to small amounts of Cr VI can lead to damage of the respiratory, gastrointestinal, and immune systems, as well as the kidneys, liver, blood, and skin. Despite cleanup efforts, Cr VI groundwater contamination remains a problem in Hinckley and other locations across the globe. A study by the Environmental Working Group found that of 35 US cities tested, 31 had higher levels of Cr VI in their tap water than the public health goal of 0. Molecular Covalent Compounds The bonding characteristics of inorganic molecular compounds are different from ionic compounds, and they are named using a different system as well.
Gas Properties
The charges of cations and anions dictate their ratios in ionic compounds, so specifying the names of the ions provides sufficient information to determine chemical formulas. However, because covalent bonding allows for significant variation in the combination ratios of the atoms in a molecule, the names for molecular compounds must explicitly identify these ratios. Compounds Composed of Two Elements When two nonmetallic elements form a molecular compound, several combination ratios are often possible. For example, carbon and oxygen can form the compounds CO and CO2. Since these are different substances with different properties, they cannot both have the same name they cannot both be called carbon oxide. To deal with this situation, we use a naming method that is somewhat similar to that used for ionic compounds, but with added prefixes to specify the numbers of atoms of each element.
