potentially get any worse. How the contents of instant cold packs help them work. 2. Instant hot and cold packs work by using chemicals that wither absorb a lot of heat quickly or release heat when absorbed in water, when a process absorbs a lot of heat it’s called an endothermic reaction ; when a process releases a lot of heat it’s called an exothermic reaction, the chemical ammonium nitrate Is quite often used in cold packs because it absorbs a lot of heat when soaked in water, water and…

to a different neuron, and incite an action potential. This whole process occurs all the time will billions of neurons. It is an exceedingly complex system that is vital for the survival of species. What if the sodium channels were blocked when there is an impulse or stimulus present. In this lab experiment, we will find out how two chemicals, Lidocaine and TTX, affect sodium channels and action potentials. Both of these chemicals bind to sodium channels, and prevent sodium from entering the…

Lab #4: Physical or Chemical Changes Formal Report Purpose Everything can change from one substance to another, but the creation and the end of some objects never happen. On a beautiful day on the fourth of December in 2015, the class of SNC1D5 started a lab on different kinds of molecules. The objective of this lab was to investigate the chemical and physical changes between different substances. With chemical reactions, reactants or heat, substances can change from one substance to another…

The lab we conducted involved a process called the Maillard Reaction. When it comes to cooking meats, heating the food causes the proteins, especially those nearest the surface of the meat, to denature. These denatured proteins become more chemically reactive to other molecules in their environment. One of the primary reactions that occur when browning meats and many other foods is called the Maillard Reaction. The Maillard Reaction is a non-enzymatic chemical reaction between amino acids and…

things, many biological processes are too inefficient to occur on their own. With the help of enzymes, or protein catalysts, the efficiency of these chemical reactions becomes much greater having less of an effect on the cells they occur in. Enzymes help to increase the overall rate of these reactions by lowering the energy needed to activate this process during the transitional phase. They can do this without being consumed or permanently altered by the reaction, as well as not disrupting the…

Background Research Chemical kinetics is the research of chemical processes which relates to the mechanisms and rates of chemical reactions (Sciencebuddies). The mechanisms describe variations of each molecule during the chemical action such as which bond is broken, which bond together newly, and how the three-dimensional shape of the chemical changes (Sciencebuddies). The rate of the reaction is measuring the speed of the chemical reactions (Sciencebuddies). Study of chemical kinetics would…

Martha Garcia November 10, 2017 Chemical Weathering Background Chemical Weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. It occurs in almost all types of rocks, smaller rocks are susceptible, because they have greater surface area, more common where water is, because water is important to many of the chemical reactions, when water is slightly acidic, which is called ocean acidification. Ocean acidification is…

that want to put up hurriedly manufacturing chemical plants. Engineering profession, just like in many other professions is confronted with many ethical responsibilities. The study is exceptionally important to the practicing engineers since it presents viewers with ethical guidelines that should be followed when undertaking any engineering work in the community and the codes of ethics that become an integral part in guiding their decision-making process. The study ‘Incident at Morales’…

Fair Research Paper Honors Chemistry Group Number 8 Research Paper The science fair topic at hand is whether or not chemical compounds affect water 's heat resistance/reception. In other words, how does the temperature of water (H2O) change when chemical compounds - such as sodium chloride and sucrose - are added? In this experiment, the independent variable is the chemical compound being tested while the dependent variable is the temperature of the water. The constants are the surface…
