Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its "bang" from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.

What is the most simple chemical reaction?
Some common examples of physical changes are: melting, freezing, condensing, breaking, crushing, cutting, and bending. Some, but not all physical changes can be reversed. You could refreeze the water into ice, but you cannot put your hair back together if you don't like your haircut!
Is fire a chemical reaction?
In a more formal sense, chemistry is traditionally divided into five major subdisciplines: organic chemistry, biochemistry, inorganic chemistry, analytical chemistry, and physical chemistry.
Is baking a chemical reaction?
Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. For example, chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car's engine.
What are the bad chemical reactions in everyday life?
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
What are 3 examples of physical changes?
An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction.
What are the 5 types of chemistry?
Oxygen is made through a chemical reaction between hydrogen peroxide and yeast. A glowing splint is used in the classic test for pure oxygen. Carbon dioxide is generated using baking soda and vinegar. A lighted splint is used to test for the CO2.

Answer. ⇒ The reaction that produces the most harmful radiation is Fission reaction.
What type of reaction releases energy?
The vast use of ethylene is what makes it the “World's Most Important Chemical.” As demand has risen, U.S. production of ethylene has steadily increased since 2008 and is now viewed as a leading indicator of growth in the manufacturing sector.
What are 5 examples of a chemical equation?
Carbon: Carbon is the foundational element for all life on Earth.
What are the 7 types of reactions?
When chemical reactions are not properly managed, they can have harmful, or even catastrophic consequences, such as toxic fumes, fires, and explosions. These reactions may result in death and injury to people, damage to physical property, and severe effects on the environment.
What are the 11 types of chemical reactions?
Within biological systems there are six major classes of biochemical reactions that are mediated by enzymes. These include group transfer reactions, the formation/removal of carbon-carbon double bonds, isomerization reactions, ligation reactions, hydrolysis reactions, and oxidation-reduction reactions.
What reaction produces oxygen?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
What is the coolest chemical reaction?
Fire. Arguably the first chemical reaction used in a controlled manner was fire. However, for millennia fire was seen simply as a mystical force that could transform one substance into another (burning wood, or boiling water) while producing heat and light. Fire affected many aspects of early societies.
Who is the king of chemical reaction?
When all of the reactants of a reaction are completely consumed, the reaction is in perfect stoichiometric proportions.
Which reaction is most harmful?
Fire is a particular type of chemical reaction in which the atoms in a fuel (the material that burns) react with oxygen. The reaction produces different molecules, such as carbon dioxide and water, and releases energy in the form of light and heat. Most fires require three things: oxygen, fuel, and heat.
What are the top 10 chemical reactions?
Class A: solid materials such as wood or paper, fabric, and some plastics. Class B: liquids or gas such as alcohol, ether, gasoline, or grease. Class C: electrical failure from appliances, electronic equipment, and wiring. Class D: metallic substances such as sodium, titanium, zirconium, or magnesium.

The five kinds of chemical reactions are combination, decomposition, single displacement, double displacement, reduction and oxidation.
What is the most important chemical for life?
Chemical reactions are foundational to all cooking. Knowing how to apply the reactions is helpful…and understanding why they work takes your culinary skill to the next level and will open up the doors to greater creativity.
How do chemical reactions affect us?
The chemical composition of a boiled egg is different from that of a raw egg. Heat causes denaturation of protein chains, converting egg into a solid mass which can not be converted back into its solid form. Therefore, it is a type of chemical change.
What are the important chemical reactions in living things?
When water is boiled, it undergoes a physical change, not a chemical change. The molecules of water don't break apart into hydrogen and oxygen. Instead, the bonds between molecules of water break, allowing them to change physically from a liquid to a gas.
