Ammonium dichromate looks pretty cool when you burn it:
Aluminum meets bromine:
Caesium and fluorine are a reactive combo:
Water and liquid nitrogen make pretty good cover for escape:
Take one part hydrogen peroxide, one part potassium iodide, and a little soap, and you’ve got yourself a tiny mushroom cloud:
Hereof, what elements when combined explode?
Now this is an effective way for kids to remember the names of elements… have the elements explode! Five out of the six Alkali metals react with air and water: Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), and Caesium (Cs).
What is the most explosive chemical?
Here are five of these non-nuclear chemicals which all explode via the rapid release of gas.
TNT. One of the most commonly known explosive chemicals is trinitrotoluene, or TNT, which has featured extensively in video games and films.
What is the chemistry of an explosion?
An explosion is a rapid increase in volume and release of energy in an extreme manner, usually with the generation of high temperatures and the release of gases. Supersonic explosions created by high explosives are known as detonations and travel via supersonic shock waves.
What chemicals can explode?

What chemicals make fire when mixed with water?
If a few drops of water are added to a mixture of solid silver nitrate and powdered magnesium the mixture bursts into flames. The water dissolves the silver nitrate to make a highly concentrated solution. An exothermic displacement reaction occurs which ignites any excess magnesium.
What chemicals mix to make fire?
Then a drop of sulfuric acid is drawn into a pipette and the pipette is dipped in potassium permanganate to pick up some crystals. Then the sulfuric acid is squeezed out causing it to mix with permanganate and form manganese heptoxide that instantly sets the tissue on fire.
What are the five types of chemical reactions?
The major types of chemical reactions are:
Combination or Synthesis Reaction.
Displacement or Replacement Reaction.
Acid Base Reactions.
What are the four main types of chemical reactions?
Different Types of Chemical Reactions
Synthesis / Direct Combustion. These chemical reactions occur where two or more substances react together to form just one product.
What is in a chemical reaction?
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What are the new substances that are formed in a chemical reaction?
A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.
Why can a chemical change not be reversed?
Because chemical changes produce new substances, they often cannot be undone. For example, you can’t change ashes from burning logs back into wood. Some chemical changes can be reversed, but only by other chemical changes. For example, to undo tarnish on copper pennies, you can place them in vinegar.
What elements mixed together make an explosion?
Sodium, potassium, lithium, and all the other elements in the first column of the periodic table (excluding hydrogen) are what are known as alkali metals, and all of them are extremely reactive. Mix sodium and potassium together and — according to Poliakoff — you get an especially reactive alloy.
Are chemical changes reversible?
Many chemical reactions are NON-REVERSIBLE CHANGES .You cannot turn a baked cake back into its raw ingredients. Some chemical reactions can be reversed, and re-formed into the original substances. These are REVERSIBLE CHANGES. As in every chemical reaction, no mass is lost or gained.
What is the formula for a chemical reaction?
A chemical reaction equation gives the reactants and products, and a balanced chemical reaction equation shows the mole relationships of reactants and products. Often, the amount of energy involved in the reaction is given. Dealing with the quantitative aspect of chemical reactions is called reaction stoichiometry.
What are the signs of a chemical reaction?
Yes; new substances formed, as evidenced by the color changes and bubbles. Some signs of a chemical change are a change in color and the formation of bubbles. The five conditions of chemical change: color chage, formation of a precipitate, formation of a gas, odor change, temperature change.
What is the chemical equation?
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side. The first chemical equation was diagrammed by Jean Beguin in 1615.
What are some examples of chemical reactions?
Combustion reactions, such as a burning candle, are also examples of the chemical change through the combination of wax and oxygen in a reaction that produces heat, light, and carbon dioxide. Decomposition, the opposite of combination, occurs when a single substance breaks down into two or more different substances.
What is types of chemical reaction?
We’ll learn about the five major types of chemical reactions: synthesis, decomposition, synthesis, single replacement (also called single displacement) and double replacement (also called double displacement). In a decomposition reaction, a compound breaks down into simpler elements or compounds.
What can cause a chemical reaction?
Let’s start with the idea of a chemical reaction. Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules. That’s it.
What is the difference between the reactants and products of a chemical reaction?
Chemical reactions usually occur between substances that are referred to as chemical reactants. At the end of the chemical reaction, reactants are usually consumed and are transformed into a new substance. On the other hand, products are end points of chemical reactions, and they are produced at the end of the process.
What is an exothermic chemical reaction?
An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants → products + energy.
What are the factors that affect the rate of chemical reaction?
The factors that affect reaction rates are:
surface area of a solid reactant.
concentration or pressure of a reactant.
nature of the reactants.
presence/absence of a catalyst.
What is used to make TNT?
First, toluene is nitrated with a mixture of sulfuric and nitric acid to produce mononitrotoluene (MNT). The MNT is separated and then renitrated to dinitrotoluene (DNT). In the final step, the DNT is nitrated to trinitrotoluene (TNT) using an anhydrous mixture of nitric acid and oleum.
