electric current to drive an otherwise non-spontaneous chemical reaction. During electrolysis‚ hydrogen atoms (H2) are reduced at the cathode whereas the oxygen atoms (O2) are oxidized at the anode. There were three different solutions used in the experiment in order to have a better understanding of electrolysis reactions. From each solution‚ reaction equations were produced. The reactions could be observed from the indicators used. The reactions showed that hydrogen ions were produced at the anode‚ making

Reaction Paper 1 Reaction Paper 1 The movie is about the responsive brain and the behaving brain. The brain is one of the most dynamic systems on the planet‚ for as much work the brain does and its complexity. It’s amazing how a simple thing like touch can be communicated through emotions. The movie talks about how the touch of a mother affects how a both a healthy baby develops and premature babies. The touch of the mother helps the baby develop with regards to their weight‚ how active they

Reaction Paper—Nonfiction ENG/125 August 29‚ 2012 Dr. Stripling Reaction Paper—Nonfiction When reading I came across some interesting non-fiction story and letter written by well known authors. They were all good but there was two that I had the most reaction to. When I came across these two letters I felt like I had a connection with the author. The letter Salvation by Langston Huge‚ when I read could relate to it cause I to come from a christen background‚ and in the story by Lam about

The error in this step was caused by the variable heating of the solution to prevent bubbling of the solution. The reaction of copper with nitric acid resulted in a brown toxic gas‚ As the copper dissolved‚ the solution slowly turned blue because of the copper ions. this is the balanced equation for the reaction Cu(s) + 4H+(aq) + 2NO3-(aq)---> Cu2+(aq) +2NO2(g) + 2H2O(l) The reaction of aq copper nitrate with sodium hydroxide was the turning of the solution to a blue color‚ when water was added a

Chemical Reactions and their Classifications 26 October 2012 Abstract: Ordinary laboratory ware was used to determine how many of what type of chemical reactions occurred. This yielded three decomposition reactions‚ four substitution reactions‚ and three metathesis reactions. Introduction There are many different types of chemical reactions in the study of chemistry; A composition reaction (also known as synthesis) is defined as the reaction that occurs when two single compounds combine in

Enzymes are proteins or nucleic acids that catalyze reactions. They are able to speed up reactions by reducing the activation energy of a reaction. Each kind of enzyme has a specific shape that matches its substrate so it can bind to its active site. Enzymes convert their substrates into a product. Enzyme activity are affected by factors such as temperature‚ pH‚ and time. If an enzyme is exposed to extreme heat‚ it will become denatured‚ that is‚ to become deformed and lose its original shape which

Exothermic Reactions Brr! Exclaimed a kid who touched citric acid and baking soda combined. When those two mix‚ it creates a cold endothermic reaction. An exothermic reaction is a reaction that releases energy in the form of an increase in temperature. Endothermic reactions are reactions that absorb energy and cools down surroundings. (Many examples give away exo and endothermic reactions). So listen up! To begin with‚ a chemical reaction in which energy is released is an exothermic reaction. Heat

English 100-05 5 October 2012 Reactions towards the Homeless In the article “Charity Means You Don’t Pick and Choose‚” Patricia O’Hara talks about many encounters with homeless people. She gives examples of people reacting with kindness‚ indifference‚ and contempt. At the end‚ she determines that people should consistently be kind regardless of circumstances. O’Hara frequently talks about the problem of how people who are doing well in life shouldn’t treat the homeless any different. People

objective: In this experiment‚ I decided to find out how temperature would affect endothermic reactions compared to exothermic reactions. An endothermic reaction absorbs energy in the form of heat. This reaction feels cold because it is taking heat away from its surroundings. It also releases gases. An exothermic reaction is a reaction that releases energy as heat. Since the energy is released‚ the exothermic reactions feel hot. Methods/Materials I did three experiments. I mixed lemon juice and baking
