Reactions that require energy are called Endothermic. The following reaction is between Sulphuric Acid (H2SO4) and Sodium Hydroxide (NaOH) to give Sodium Sulphate (Na2SO4) and water (H20):H2SO4 + 2NaOH --> Na2SO4 + 2H2O This equation is balanced. Counting the individual atoms on both...
Reactions that absorb free energy are called: A. potential B. kinetic C. exergonic D. endergonic Catabolic reactions are tightly coupled to reactions that require energy. Can an enzyme make an endergonic reaction exergonic? Why or why not?
The oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), namely, so-called oxygen electrode reactions, are two fundamental half-cell reactions in the energy storage and conversion devices, e.g., zinc–air batteries and fuel cells. However, the oxygen electrode reactions suffer fro...
The electronegativity of the nitrogen and oxygen atoms is significantly higher than that of sulfur, but the rates of cycloaddition reactions are lower. Perhaps the reason for this unexpected effect may be the interaction of the sulfur-carbon multiple bond orbitals with the orbitals of oxygen or ...
Three examples of chemical reactions are: 1. Hydrogen peroxide being broken down into water and oxygen. 2. Macromolecules like proteins being broken down into the amino acids that make them up during digestion. 3. The formation of a disaccharide like sucrose, which results from the joining of ...
However, these reactions often require activation energy (discussed in more detail in the module Chemical Bonding: The Nature of the Chemical Bond), which can be provided by a ‘spark’ or source of energy for ignition. Fuel, oxygen, and energy are the three things make up what is known ...
“smoke”. the reactants require a minimum amount of energy i.e. activation energy to undergo combustion. definition: the reaction in which a fuel burns in the presence of oxygen to form carbon dioxide, water, heat and light is called a combustion reaction. combustion reactions chemistry ...
The reactions that allow energy to be extracted from molecules such as glucose, fats, and amino acids are calledcatabolic reactions, meaning that they involve breaking a larger molecule into smaller pieces. For example, when glucose is broken down in the presence of oxygen, it’s converted into...
Whether outside the body or inside the body, when oxygen reacts with molecules producing carbon dioxide, water, and energy, the process is called combustion. Even though our cells combust the molecules differently, the calorimeter provides an accurate caloric value because the end products of the...
If breathing is severely impaired, a breathing tube may be inserted into the windpipe (trachea) through the person’s mouth or nose (intubation) or through a small incision in the skin over the trachea, and oxygen (if needed) is given through the breathing tube. Blood pressur...
