INTRODUCTION TO CHEMICAL BONDS CHEMICAL BOND Definition: A chemical bond is defined as a force that acts between two or more atoms to hold them together as a stable molecule. Main types of bond: 1. Ionic or electrovalent bond‚ 2. Covalent bond‚ 3. Coordinate covalent bond Forth type of bond: Metallic bond: The type of bonding which holds the atoms together in metal crystal. Valence electron: The electrons in the outer most energy level in an atom that takes part in chemical

traditions are passed from generation to generation to sustain our base and beliefs. However sometimes certain traditions may fade within in time if not emphasized and practiced by leaders. In order to build a strong foundation it’s important to often remind ourselves of the bond that upholds us. Passing along the core values‚ traditions‚ customs and history of our Corps is necessary to promote good order and discipline. Drills are an example of one of the many traditions that have been part of the history

Farriers are a horse’s best friend because they know the anatomy and behavior of the horse to take better care of them and more needed in todays society. People say we don’t need farriers because of how much they charge to do the work.Or they say they can do it themselves. Which in reality they never do. They find something else that needs done and they push back on trimming their horse’s feet. They say that they don’t need anyone else to do it for them. In reality people need farriers. Farriers

Covalent Bonds Covalent bonds are formed when atoms share electrons‚ one from each atom in a single bond‚ to form electron pairs‚ usually making their outermost shells up to eight electrons by this means. This would make them more stable‚ less reactive and an electronic structure like a noble gas. They are most frequently formed between pairs of non-metallic elements. Non-metallic elements usually have from four to eight electrons in their outermost shells‚ the so-called valency electrons‚ which

of a component causes the equilibrium to shift to the side from which the component was removed. D. Is this reaction endothermic or exothermic? How do you know? When acid is added to water the reaction is strongly exothermic. Because the hydrogen ion is so tiny‚ a large amount of charge is concentrated in a very small

Hydrogen and the Noble Gases Hydrogen is the chemical element with atomic number 1. It is represented by the symbol “H”. It is an odorless‚ nonmetallic‚ tasteless and highly explosive gas. Hydrogen is the lightest and most abundant chemical element in the universe. It forms 1- ions when combined with metals‚ and 1+ ion when combined with non-metals to form acids. Hydrogen is “the fuel of life”; without it to combine with oxygen we would not have water. Water is made of two parts hydrogen

seem more suitable than hydrogen. The possibility of hydrogen as a fuel is ever increasing‚ with the advantages outweighing the disadvantages more every year. Car manufactures are already making cars that are hydrogen powered‚ although they are either prototypes or extremely limited production runs‚ but cars such as the Honda Clarity prove that hydrogen powered cars really are not a thing of the future‚ but a thing of the present.

Kinetics of Hydrogen Peroxide February 22‚ 2007 Chem. 1130 TA: Ms. Babcock Room 1830 Chemistry Annex PURPOSE OF THE EXPERIMENT Kinetics of Hydrogen Peroxide The major purpose of this experiment is to determine the rate law constant for the reaction of hydrogen peroxide and potassium iodide. In this experiment‚ the goal will be to try to measure the rate law constant at low acidity‚ since at low acidity‚ anything less than 1.0 x 10-3M‚ the effect of the hydrogen ion is negligible. To calculate

I believe that having vaccines and getting vaccinated is very important in the United States. Vaccines protect your life from deadly diseases‚ it protects the lives of the people around you from getting a disease from you‚ and it will protect the lives of the future generations to come after you. This is why it is important for everyone in the United States to be properly vaccinated. Every time you are getting a vaccine you are protecting yourself a little more. Vaccines fight off very dangerous

Why is art important? The purpose of my presentation today is to answer the following question: Why is art important? and to show you the influence of art on education. However‚ first of all‚ there is a question What is art? As it is stated by philosopher Veron: "Art is an external manifestation by means of lines‚ colours‚ movements‚ sounds‚or words‚ of emotions felt by man." on the other hand Lars Vilks who has the PhD in history of art claimed that Art cannot be defined. If you are sensitive enough
