Chemical element

and show how six elements ( Lithium, Sodium, Potassium, Rubidium, Cesium, Francium ) reacted if they were added to water. Each scientist had did this experiment on each element except Francium so, we inferred that Francium had the worst reaction and must be dangerous. So because of curiosity, we have conducted the same lad to see how these elements reacts ourselves. In this lab, my group and I had to examine chemical reactions. We had to record our observations and list six elements in their…

hair growth all deal with chemistry in their own way. They all have certain chemical reactions and chemical changes that affect the way our bodies work. Even though we study different curriculums during chemistry such as the chemical equations, chemical reactions, and other things we have learned go far beyond what is said in class. During food digestion there are chemical and physical changes occurring. One chemical change for example would be, metabolic rate which is the rate of…

light produced by the Sun is blocked by the atmosphere, but some light does still reach Earth? Ultra violet light can be detected using electronic devices. Important terms that will be discussed in this paper are ultraviolet light, photochromism, chemical reactions, and absolute zero. Relating to electromagnetic radiation having wavelengths shorter than those of visible light but longer than those of x-rays. Ultraviolet radiation is emitted by the sun and some of its absorbed by the sun and…

Chromate The Prefix word “poly” implies to the word many, but even ions of two atoms are usually referred to as polyatomic. Majority of the Polyatomic ions that are used with Oxygen will have the word “ate” in them. Nitrate is an example of a Polyatomic Ion. Polyatomic Ions are referred to as a radical, and less commonly, as a radical group. There are many differences between a polyatomic ion and a compound. Polyatomic ions are composed of two or more atoms that are linked to covalent…

quantities of substances taking part in a reaction or forming a compound. The coefficients in a balanced chemical equation represent moles of reactants and moles of products. The mole ratio of reactants and products in a balanced equation must remain constant. Stoichiometry relates to cookies because all the ingredients mixed together make the cookies. In the process of mixing elements in during chemical reactions the precision of measures of…

change happen. Chemical change is the process of bonds breaking and forming new ones. All the atoms have to stay in the compound in a chemical change, but you…

Chemical, biological, radiological and nuclear (CBRN) weapons, also referred to as weapons of mass destruction (WMD), continue to pose a significant threat to all living things on earth. WMD are very different from conventional weapons. These weapons can be used in several different ways and the effects can range from environmental destruction, to incapacitating humans or animals, or even killing them. The Department of Defense (DOD) Strategy for Countering Weapons of Mass Destruction is…

earth`s surface. Chemistry can relate to chemical reactions, one of the chemical reactions that occur is the creation of acidic rain. It can also relate to sublimation after the sinkhole occur, and to the rocks in a sinkhole and what they 're made of. One of the chemical reactions that occur that is based upon hydrogen and carbon dioxide is “H2O(l) + CO2 9(g) -> H2CO3 (aq)’’ (Brian Rohig). The outcome of this equation is acidic rain. In chemistry we use chemical equations to show how…

Introduction Copper is an element that can be typically obtained from copper ore (minerals) in the Earth’s crust(1). The ore is initially mined then goes through processes to recover copper(2). Copper is important as it many chemical and physical properties. Copper is a good conductor of electricity and is malleable (the ability to be bent) which is why copper is used in electrical wiring. It is also used in bronze and brass as an alloying agent(3). Chemists use a sequence of chemical reactions…

cycle, with weather influencing the way the water moves through the earth. Chapter 15 “The Ladder of Life” All living organisms follow the same ladder of life. . “ All living things are made of cells the chemical factories of life.” (Hazen & Trefil 252). But it goes even further than that, chemical Compounds, microscopic cells, cells to organs, to organ systems and then organisms. Even then organisms are categorized by kingdom ,phylom, class, order , family, genus, species. Everything living…
