Chemical reaction

A chemical reaction is the interaction of two or more chemicals that produces a new chemical compound, most reactions require an increase in temperature, pressure, surface area, concentration or the inclusion of a catalysts to speed up the rate of reaction. Chemical reactions can be found in everyday life, without many of us knowing. Either it be a soluble tablet in water, or photosynthesis in a plant. The prerequisites for a reaction are known as the 'Collision Theory '. As stated by M. Ferguson

Finding the Ratio of Moles and Reactants in a Chemical Reaction The main objective is not only to reach the optimum ratio to generate the greatest amount of heat and temperature, but also to maintain a constant volume throughout the entire experiment. Jenny Gao Sophia Hu 9/11/15 Procedure: My partner and I measured the temperature of NaCIO (bleach) and Na2S2O3 to prevent any misleading data. We then measured 250mL of each solution and poured 5.0mL of NaCIO and 45.0mL of Na2S2O3 in a styrofoam

has increased or decreased during a chemical reaction. Hypothesis: There will be no change in mass for reaction one and each reactant. From the information of the Law of Conservation of Mass, there will not be any change in mass during and after the chemical reaction. There will be no change in mass for reaction two and each reactant. From the information of the Law of Conservation of Mass, there will not be any change in mass during and after the chemical reaction. Materials: • Eye protection • Test

Examining the Percentage Yield of a Chemical Reaction Komal Maan 470883 Ms. Chandan April 28th, 2015   Introduction: Numerous factors can determine the percentage yield of a chemical reaction. Such as the nature of the reaction, the conditions in which the reaction is carried out and the nature of the reactants used in the reaction. In this investigation the percentage yield was to be determined using the following chemical reaction: Fe(s) + CuCl₂ (aq) FeCl₂ (aq) +Cu(s) Steel wool was used

The diverse types of chemical reactions include Combination Reaction, Decomposition Reaction, Displacement Reaction and Oxidation Reaction. Combination reaction is a reaction where two reactants are combined into one product (Helmenstine, 2014). An example of this in everyday life is when we digest food in our stomachs, the acid in the stomach reacts with the molecules contained within the food and breaks them down. A decomposition reaction is a type of chemical reaction where one reactant yields

In this lab, we tested how chemical reactions happen when enzymes and reaction rates are effected. For the chemical reaction, we broke down the substrate ONPG into galactose and o-nitrophenol. Using ONPG as the substrate allowed us to see what was actually going on. When breaking down ONPG, the o-nitrophenol turns yellow, unlike lactose which is colorless. There are two ways in which we can manipulate the reaction rate and activation energy in this experiment. Increasing the heat by exposing enzymes

to understand how two different reactions can lose mass in a chemical reaction, and to learn how to arrive to the results in an organized way of recording data. The two balanced equations that we worked with were: NaHCO_(3(s))+HCl_((aq) )→NaCl_((aq))+CO_(2(g))+H_2 O_((l)) and; Na_2 CO_(3(s))+2HCl_((aq))→2NaCl_((aq))+CO_(2(g))+H_2 O_((l)) The procedure to obtain the mass lost for these two reactions was to first calculate the mass of HCl. For the first reaction, which was sodium bicarbonate, the

: During each reaction, something happened. During reaction 1, after adding the nitric acid a red-brown gas was created. The copper first turned green after a few minutes turned into a blue solution. Reaction 2, When acid was added a blue precipitate formed. Reaction 3, when heated the solution turned into a black precipitate. I noticed that the darker particles were denser than water. Dark particles began to settle to the bottom. Reaction 4, Sulfuric acid dissolved the black precipitate back to

Chemical, as well as physical reactions are key factors in the study of Biology. Reactions have many different forms including reaction times, products, reactants, etc. This laboratory experiment aimed to allow students to become familiar with oxidation reactions and enzymes. Enzymes are proteins that are used to enhance the rate of reaction. Without enzymes the reaction time will be a lot longer than that with the enzyme, therefore making the use of enzymes essential to students who are completing

Problem: There are thousands of chemical reactions that occur in an organism that make life possible. Most of these chemical reactions occur too slowly on their own. Enzymes are protein catalysts that speed up chemical reactions in a cell. Catalysts are not changed by the reactions they control, and are not used up during the reaction. Enzymes therefore, can be used over and over again. Enzymes are large complex proteins made by the cell and allow chemical reactions to take place at the temperature
