Abstract Chemical equilibrium occurs when a reversible reaction is happening forward and backward‚ at the same time by the same amount‚ is equal. Two procedures were made. First is the Effect of Concentration on Equilibrium. The solution became orange when it was diluted with ammonium hydroxide and the solution became yellow when water was added to the solution. In the second‚ Effect of Temperature on Equilibrium‚ the solution turned into a light brown gas when it was placed in the refrigerator

fires and is a tool that you should carry when you go into the woods. Cerium and the element before‚ lanthanum are both used for dramatic spark effects in movies. They get a big block of it and put it to a grinder. Its atomic number is 58 and its chemical symbol is Ce. The last element I will discuss is neodymium. It is the best known out of the lanthanide series out of rare earths because of the one and only neodymium magnets. They are the strongest magnets in the world and there are many purposes

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to

Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate

Defining steroid abuse can actually be very difficult compared to other types of drugs. For example‚. An individual who drinks all day is going to stick out like a sore thumb‚ and while some can get away with it for a time eventually the abuse shows through. This is not the case with steroid abuse. Anabolic steroids do not have the ability to alter our mind or perception like alcohol or other drugs. There is of course the issue of roid rage that often comes up‚ but at steroidabsue.com we cannot give

The second way that steroids most likely improve athletic performance is due to the infamous phenomenon know as the placebo effect. Although I cannot give you hard evidence or studies that prove this claim‚ I can and will explain my reasoning for this claim. As you may know‚ Major League Baseball is notorious for it’s players getting busted for performance enhancing drugs‚ aka anabolic steroids. Player’s statistics have shown a vast increase when influenced by anabolic steroids. For instance‚ the

anabolic steroids. This epidemic is spreading through our country like a wildfire. It is going unnoticed and misunderstood. Even our government has not found the money the man power or the time to deal with this killer. It can be bought wherever pleasure or illicit drugs can be found. The people who push these drugs are usually the people teenagers look up to. The drug pushers are the kids teachers‚ coaches and even their parents. It seems to me that if a parent pushes steroids on their
