Three things are usually required for a chemical explosion: a chemical reaction that occurs very rapidly‚ a large increase in gas pressure‚ and a confined-reaction vessel in which the pressure of the gaseous products can increase to a point that the gases break violently out of the container. In this chemistry and physics science fair project‚ you will use the combustion of ethanol to provide energy for a small explosion. The chemical equation that describes the combustion of ethanol is shown below

3/21/2012 Cell Growth & Division Essay Kate Nogler Mr.Lapointe When a living thing grows‚ it produces more cells through a process called cell division. Cell division is necessary for any growing eukaryotic cell structure. Cells divide through a system called the cell cycle. It is a complicated and crucial part of anatomy! Before a cell divides‚ it must grow. However‚ a cell can’t grow forever. Once a cell gets too big‚ it divides itself into two daughter cells. A cell divides because

Victoria Sanford’s book‚ Buried Secrets helps readers to understand the violence that occurred during the genocide that took place in Guatemala. This destruction happened during the 1960’s until 1996. She reviles the tragedies that happened from the standpoint of more than 400 rural Maya survivors‚ former soldiers‚ archival research and formerly classified documents. There were 626 villages and 200‚000 civilian victims that were affected by this genocide. The Guatemalan army were the ones who led

Chemical Nomenclature refers to the naming systems used with chemical formulas. This worksheet focuses on the most basic chemicals and nomenclature systems. Please read the information concerning each problem set and then attempt the problems associated with that information. The simplest compounds contain just two elements. Sodium chloride‚ NaCl‚ is an example of a binary compound. Several other examples are listed below. Potassium bromide KBr Calcium bromide CaBr2 Lithium fluoride LiF

In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to
