Overview
- A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei, and can often be described by a chemical equation. Nuclear chemistry is a …
- The power to create chemical reactions. Sub-power of Chemical Reaction Manipulation. Opposite to Physical Change Creation.
Reactions
- Biochemical reactions are mainly controlled by enzymes. These proteins can specifically catalyze a single reaction, so that reactions can be controlled very precisely. The reaction takes place in the active site, a small part of the enzyme which is usually found in a cleft or pocket lined by amino acid residues, and the rest of the enzyme is used mainly for stabilization. The catalytic ac…
- Formation of Aluminum Bromide: When Al is placed on the surface of liquid Br2 an exothermic reaction occurs. The Al is oxidized to Al3+ by the Br2, which is reduced to Br - ions. The ionic product, AlBr3, can be observed on the watch glass after the reaction. Formation of Sodium Hydroxide and Potassium Hydroxide: When a small piece of Na is added to a solution containin…
Reactions In Organic Chemistry
- In organic chemistry, in addition to oxidation, reduction or acid-base reactions, a number of other reactions can take place which involve covalent bonds between carbon atoms or carbon and heteroatoms. Many specific reactions in organic chemistry are name reactions designated after their discoverers.
- In a chemical reaction, there is a change of electrons, but there is no change of nuclei. Therefore, the elements present in the product of the reaction are still the same as the elements in its original reactants. There are chemical reactions that take place spontaneously without the input of extra energy, while others need the addition of heat, light or electricity.
- Formation of Sodium Chloride: Molten sodium burns when it is put into a container of chlorine gas. In the reaction a sodium ion loses an electron to form a sodium cation and a chlorine atom simultaneously gains an electron to form a chloride anion. The product of the reaction is the ionic compound sodium chloride, which is the white solid observed. Formation of Zinc Oxide: Oxidatio…
Reaction Types
- Four basic types
In a synthesis reaction, two or more simple substances combine to form a more complex substance. These reactions are in the general form: A + B ⟶ AB {\displaystyle {\ce {A + B -> AB}}} - Oxidation and reduction
Redox reactions can be understood in terms of transfer of electrons from one involved species to another. In this process, the former species is oxidized and the latter is reduced. Though sufficient for many purposes, these descriptions are not precisely correct. Oxidation is bet...
- Chemical reactions can be classified into a few categories. The simplest is probably synthesis, where two or more molecules or atoms combine into a new molecule. For example, iron plus oxygen forms iron oxide, or rust. The opposite of synthesis is analysis, or chemical decomposition, where a molecule breaks apart into its constituents. This occurs when the electr…
Kinetics
- The speed at which reactions takes place is studied by reaction kinetics. The rate depends on various parameters, such as: Reactant concentrations, which usually make the reaction happen at a faster rate if raised through increased collisions per unit time. Some reactions, however, have rates that are independent of reactant concentrations. These are called zero order reactions. Sur…
Equations
- Chemical equations are used to graphically illustrate chemical reactions. They consist of chemical or structural formulas of the reactants on the left and those of the products on the right. They are separated by an arrow which indicates the direction and type of the reaction; the arrow is read as the word "yields". The tip of the arrow points in the direction in which the reaction procee…
Combination
- A combination reaction is when two or more substances react to form one new substance; essentially, when A + B = AB, as in the example of hydrogen and oxygen combining to make water. The reactants can be either two elements, as in the water example, or two compounds AB + CD = ABCD, such as when magnesium oxide combines with carbon dioxide to make magnesium carb…
