☕ Read moreWhen it comes to natural sunscreens, the active ingredient is often one of two substances: zinc oxide or titanium dioxide. Both substances work by sitting on the surface of the skin and forming a physical barrier to the sun’s harmful rays. But what exactly is the difference and which one is better? Furthermore, is there any health risk associated with either of them? Which…
☕ Read moreOxidation numbers are bookkeeping numbers. They allow chemists to do things such as balance redox (reduction/oxidation) equations. Oxidation numbers are positive or negative numbers, but don’t confuse them with positive or negative charges on ions or valences. Oxidation numbers are assigned to elements using these rules: Rule 1: The oxidation number of an element in its free…

The compound has several industrial uses, and There are two forms of magnesium oxide The combination of magnesium oxide and water results in magnesium hydroxide along with a Magnesium generally reacts weakly with water, unless the water is at a high temperature. It will produce…
☕ Read moreCalcium oxide has the chemical formula CaO and is a white crystalline substance. Because calcium oxide does not occur naturally, its production is generally from calcium carbonate or limestone. There are many commercial uses for this compound because it readily forms solutions with other substances like silicates. Some other uses of calcium oxide in other industries include…
☕ Read moreThe zinc oxide is industrialized to make rubbers, ceramics, and used in many different medications. ZnO is produced in several ways including smelting, laboratory synthesis, and wet chemical processing. The most common ways to create the oxide is through smelting, which includes the direct or indirect processes. In the indirect process, zinc is melted at 907 degrees Celsius…
☕ Read more12 December 2007 Chemists in Japan and France have produced a new iron oxide with a sheet-like structure that could be used in fuel cells and sensors. The team produced the compound by gentle reduction in a way that may also yield other unusual and potentially useful crystalline structures. Hiroshi Kageyama from the University of Kyoto and colleagues started with a conventional…

☕ Read moreAlthough aluminum oxide is certainly abrasive, it is also a skin irritant with a very questionably safety record. In any case, it is unquestionably unpleasant. If it gets into your eyes, it can scratch your cornea. If it gets into your ears, it can cause earaches. If it gets into your mouth, you will experience the unpleasant sensation of tooth enamel grinding away until it’s…

☕ Read moreWhat Is It? Nitric Oxide is a gas inside your body that helps the cells in your system communicate with each other. It is a compound that consists of one oxygen atom and one nitrogen atom. This gas is produced when Arginine, an amino acid, is broken down by enzymes. Scientists claim this gas has almost unlimited functions in the body, controlling blood circulation and regulating…

Rules for assigning oxidation numbers The oxidation number of a free element is always 0. The oxidation number of a monatomic ion equals the charge of the ion. Fluorine in compounds is always assigned…
☕ Read moreQuestions, Page 123: 1) Does either bar graph reveal a repeating, or cyclic, pattern? Describe any patterns you observe. By looking at both bar graphs side by side, we noticed that the number of atoms added to the element directly correlated to the boiling points (in °K). The more atoms added, the higher the boiling point. 2) Are these graphs consistent with patterns found…
