There are eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species

immediately get the reaction paper written so I won’t forget my reading. Through this reading I learned sometimes that isn’t the smartest way to write a paper. It is very important to read actively and pay attention to what you are reading. I have been carried by the reading many times and never really thought about the purpose in depth. After reading this section of the text I have learned the importance of making sense of what you are reading. Sometimes you may read an article‚ essay or poem and take

PUTTING IT TOGETHER: Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double

CONCLUSION The experimentally obtained data collected for the reaction between IO3- and HSO3- at various temperatures is clearly supported by the Arrhenius equation. Referring to Graph 1.7‚ the line of best fits clearly passes through most of the data points displaying a linear relationship between temperature and the rate of the reaction. The R-squared of the graph which is a statistical measure of how close the data are to the fitted regression line is 0.9818. This number is extremely low which

combination of substances. The combination of substances often causes reactions‚ and one of the main groups of reactions is the single-replacement reaction. In Amrita University’s explanation of single replacement reactions‚ a single replacement reaction is defined as a “chemical reaction in which a more reactive element displaces a less reactive element from its compound.” The general formula for single displacement reaction is: AB + C A + BC. This formula shows element A being replaced in its

Cations and Anions Reaction Introduction: This experiment seeks to explore different chemical reactions conducted in the lab. A cation is defined as positively charged ions‚ which are K+ and Pb2+ in this experiment‚ and an anion is termed as negatively charged ions‚ which are CrO4 2- and NO3 2-. The major objective of this lab experiment was to examine the reaction between cations and anions‚ as well as observing‚ and documenting the chemical reactions. We will be demonstrating the reaction between a solution

Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

Purpose: The purpose of this experiment is to: determine the limiting reactant of a chemical reaction that involves iron filings and a copper sulfate solution. Second‚ to determine the mole ratios between iron and copper and to show that a single replacement reaction occurs when iron and copper sulfate react with each other. And lastly‚ to determine/calculate the percent yield to better analyze the chemical reaction between iron and copper sulfate to produce copper and iron sulfate. The method used to

From the results recorded it was identified that activity A and C had exothermic reactions‚ whilst activity B had an endothermic reaction. Each of the activities had initially begun with 23.4/8/9oC‚ however‚ within one minute of adding the 2nd reactants‚ the results began showing‚ as seen from the graph. Activity A and C had risen in temperature‚ with A gaining 4oC and in total of 2 minutes having the temperature of 27.9oC along with C increasing by 2.2oC and within 2 minutes of the experiment having
