Chemistry As Carl Sagan once said, “Chlorine is a deadly poison gas employed on European battlefields in World War I. Sodium is a corrosive metal which burns upon contact with water. Together, they make a placid and non-poisonous substance, table salt. Why each of these substances has the properties it does is a subject called chemistry.” Chemistry involves many things, from atoms to elements and their functions. It is a wide field of science with an extensive early and modern history. It also…

One of the main experiments Rutherford is known for is his Gold foil experiment. He devised a way to prove that radioactivity in particles exists in at least two forms. In the experiment tiny alpha particles were shot at a sheet of foil coated in ZnS which resulted in a small percentage went through the sheet and the rest were blocked/deflected. The percentage of particles that were able to go through the foil are now named 'Alpha Particles' and the ones that were blocked are called 'Beta…

Lesson 1: Investigating physical forces. Learning objectives: Students will be able to investigate and explain how applying or removing physical forces of varying intensity can cause objects in their environment to move, stop moving, stay at rest, or change direction. Content: Wind/ physical force:Collected from http://handmadekidsart.com/wind-power-car-races/ -The surface area contacting the wind force will affect the movement. -The high speed of the wind will allow the object to move faster.…

Robert Crowley Mr. Scott Period 3 October 30th 2015 Chemistry Introduction and Overview Elements are the substances that make up everything in the universe, known and unknown. This means that elements are what make up matter, and everything you see, hear and touch. There are 118 elements known to man, some that you may know include gold, iron and oxygen. Each of these have distinguishing qualities and they come in 3 different states of matter, solid, liquid and gas. Some of these are…

devices through electromagnetic fields instead of wires. This means that consumers no longer have to plug in their devices to charge them. Anyone who uses any kind of device that needs to be plugged in, will be able to use Fuchi MegaCorp’s inductive charger. What this device may lack in efficiency, it makes up for in dependability. A consumer will get 10x the amount of charges for their devices compared to needing to replace a charging cord after a certain amount of uses. The inductive charger…

Task 1 and 2 First ionisation energy – The first ionisation energy is the energy required to remove the most loosely held electron from one mole of gaseous atoms to produce one mole of gaseous ions each with a charge of +1. The first ionisation decreases as you go down a group. This is because the electrons are getting further away from the nucleus meaning it is easier to remove the outer electron. There is also less shielding thus allowing the outer electron to be removed much more easily. As…

Apple will charge you the most--around $200--and is not necessarily reputed as higher quality than many other services. There are a great many third party vendors that will offer to repair your broken screen for around $100 to $150. Less expensive, certainly, but there…

As one of the top 50 sports bars***CITE*** in the US, Kilroy’s Sports Bar has established a strong brand presence in the Bloomington community, and a strong image in the eye’s of the community. They have continually put in effort to distinguish themselves on promotion, and service among other Bloomington bars. Their promotion, “$3 Thursdays”, has drawn the most attendance comparatively to all other Bloomington bars (kilroyssports.com). However, they are looking to invest in any resources that…

bonds between atoms and contribute to its mass. A scientist by the name of Robert Andrews Millikan won a Nobel Prize for his study and finding of the charge of an electron. His findings greatly helped the scientific community by contributing to the Atomic Theory of Matter, which states that all matter is made out of atoms. Millikan found the charge of an electron by performing an experiment, which we now call Millikan’s Oil Drop Experiment. The Oil Drop Experiment was…

The horror of a senseless death or the sweetness of victory, how should one respond to matters of life or death? In these poems “Charge of the Light Brigade” and “Death of the Ball Turret Gunner” many may ask themselves these questions concerning life or death during war. There are many emotions involved when discussing any war. There are many states who have benefited from wars, and some who have suffered from wars. There are people who have lost their lives on the battlefield and honored as…
