What makes a reaction explosive?

For a chemical to be an explosive, it must exhibit all of the following: Rapid expansion (i.e., rapid production of gases or rapid heating of surroundings) Evolution of heat. Rapidity of reaction.

What is an example of a reaction?

A chemical reaction happens when one or more chemicals are changed into one or more other chemicals. Examples: iron and oxygen combining to make rust. vinegar and baking soda combining to make sodium acetate, carbon dioxide and water.

What are the 4 types of reactions?

Representation of four basic chemical reactions types: synthesis, decomposition, single replacement and double replacement.

What are three examples of physical changes?

Examples of physical change include changes in the size or shape of matter. Changes of state—for example, from solid to liquid or from liquid to gas—are also physical changes. Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.

What is the most powerful chemical?

One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.

Which are the most common chemical reactions in the body?

In human body the most common or you can say usual chemical reaction is respiration. Respiration is simply gaseous exchange, with release of energy. It can be stated as in oxidation reaction, where which oxygen from air get absorbed and mixed with food and then it produces energy.

What is not a chemical reaction?

These are not definite indicators; a chemical reaction may not be occurring. A change in color is not always a chemical change. If one were to change the color of a substance in a non-chemical reaction scenario, such as painting a car, the change is physical and not chemical.

What happens during a reaction?

In a chemical reaction, the atoms and molecules that interact with each other are called reactants. … No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

How do you classify reactions?

Classifying Chemical ReactionsSynthesis reactions. Two or more reactants combine to make 1 new product. … Decomposition reactions. A single reactant breaks down to form 2 or more products. … Single-replacement reactions. A single element replaces a similar element of an adjacent reactant compound. … Double-replacement reactions. … Combustion reactions.

What is a simple chemical reaction?

Examples of Simple Chemical Reactions. A chemical reaction occurs when a chemical or chemicals (the reactants) convert into another substance (the product). These reactions happen during cooking, cleaning, driving, and processes occurring inside your body, among others.

What are the 5 reaction types?

The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. Analyzing the reactants and products of a given reaction will allow you to place it into one of these categories.
