Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

I’m pretty much angry every day and it’s pretty much always for the same reason: My Chemical Romance. I first listened to MCR when I was 11 or 12. I heard a song called Cancer while creating a playlist on a website called 8tracks. My friend told me to put the song on the playlist so I did. It was a playlist inspired by The Fault in Our Stars by John Green. The song was a sad one and I didn’t really look into them much further because I already heard a few other songs (in passing‚ you could say)‚

formation of chemical bonds? Valence electrons are the electrons that are on the outermost shell of the atom’s electrons which are can be either given away‚ added‚ or to be shared. When these electrons are given away‚ added to or shared‚ there is a chemical change occurring and the compound that is formed is changed from the original elements. This is called bonding which is pretty much the realm of the electrons. It is the sharing of electrons from each atom that define the chemical bond. Because

effect chemical warfare in WW1 had on the soldier. In World War 1‚ the development and use of poison gases were created mainly to end the stalemate risen by the unexpected trench warfare . These poisonous gases‚ such as mustard gas‚ were close to impossible to avoid in or out of a trench because they were denser near the ground when released‚ causing greater suffering to those ducking for cover. It wasn’t until World War 1 that chemical warfare was given a definition‚ the use of chemical munitions

Part two Title: Enzyme Function Purpose: To observe the role of enzymes in chemical reactions and to determine the kinds of cells that contain more of the enzyme catalase. Prior Knowledge: Enzymes are proteins that assist the chemical reactions of a cell by lowering the amount of activation energy needed to start the reactions‚ thereby enabling the cell to carry out the reactions at a faster rate; enzymes
