Neon is a chemical element. Neon was discovered by two chemists named Sir William Ramsay and Morris W. Travers in the country of England. Ramsay and Travers discovered this element in the year or 1898. The word “neon” is a Greek word that means “new”. Neon was discovered through the studies of liquefied air. This element belongs to the “noble gases” group in the periodic table. The symbol for this element is ‘Ne’. Neon is in period two. The atomic number of neon is 10. The atomic mass of neon

Finding the Ratio of Moles and Reactants in a Chemical Reaction Objective The objective of this experiment was to find the mole ratios of the reactants and products for the chemical reaction, without being given the products. Neda Samya Emma & Nisha Fri. 09/11 Procedure 1 I measured the temperature of NaCIO solution and “solution B” (using the same thermometer; temperature of solutions were equal). Then recorded my data in the table. 2 I poured 5.0 ml of NaCIO into a Styrofoam cup and then

Finding the Ratio of Moles and Reactants in a Chemical Reaction The main objective is not only to reach the optimum ratio to generate the greatest amount of heat and temperature, but also to maintain a constant volume throughout the entire experiment. Jenny Gao Sophia Hu 9/11/15 Procedure: My partner and I measured the temperature of NaCIO (bleach) and Na2S2O3 to prevent any misleading data. We then measured 250mL of each solution and poured 5.0mL of NaCIO and 45.0mL of Na2S2O3 in a styrofoam

Toxic gases have been using as chemical weapons to attack people. Chemical weapons had been using in The First World War and they had been using in Iraq against Iran and Kurdistan. Also, chemical weapons have been using in Syria. Chemical weapons killed and injured thousands of people. Therefore, chemical weapons can destroy our life, cause many permanent diseases and attack our world. Chemical weapons are toxic gases, which use in the wars such as World War 1. Chemical weapons used in First World

Is A+C a chemical reaction? Yes, because of serval chemical changes happening to the solution before and after. I came to this conclusion by using three pieces of evidence. The three pieces of evidence were a ph imbalance, a dramatic density rise, and a change in electroconductivity. The first piece of evidence I found came from the density lab and the ABC lab. The evidence was a un-natural and substantial increase in density. The density was 0.75g/cm^3 for both A and C, but later A+C had a density

Indications of Chemical Reactions When elements or compounds react with each other, under the right circumstances, a chemical reaction may occur, forming a new product. According to www.rico.edu, “A chemical reaction is the change of a substance into a new one that has a different chemical identity.” However, how is it possible to see whether such reaction has actually occurred? There are various indications of when a chemical reaction has occurred. For example, such indicators include a change

Chemical terrorism presents a unique threat to the Homeland and response agencies due to the vast array of various chemical effects and availability. To illustrate this threat, an examination will be conducted into the historical development and a recent use of chlorine gas agent. Then, an investigation into chlorine’s chemical properties, its harmful effects, and required response protective/detection equipment will be conducted. Lastly, an analysis into the regulatory policy of chlorine and a current

The Toxicology of Cosmetic Chemicals; layman’s land is filled with easy-to-digest myth. SOCIETAL CONCERN; Disconnect between scientific knowledge and general public acceptance The ability to effectively communicate the safeties and dangers of chemicals between scientific professionals and the general population has been and continues to be an ongoing concern for both sides. Often, this difficult process of ensuring public safety and confidence in chemical innovation has had a certain void filled

This unti we learned about chemical reactions and this unit we mostly did labs and learned from that. There many ways to be able to get a chemical reactions. There are reaction rates and evidence for a chemical reaction. This unit the quession was what can I observe from a chemical reaction. There are many things you can observe when there is a chemical reaction. In my essay I will be talking about what I can see when there is a chemical reaction going on. This unit I was able to notice many of these
