Question: What Is The Coolest Chemical Reaction?

Why TNT is explosive?

TNT is explosive for two reasons.

First, it contains the elements carbon, oxygen and nitrogen, which means that when the material burns it produces highly stable substances (CO, CO2 and N2) with strong bonds, so releasing a great deal of energy..

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.

What are some examples of chemical reactions in everyday life?

Examples of chemical reactions in everyday life include photosynthesis, rust, baking, digestion, combustion, chemical batteries, fermentation, and washing with soap and water.

What two chemicals will explode when mixed?

Here is some combination of two household chemicals that actually explode when mixed.Bleach And Ammonia. Both are cleaning equipment that exists in your everyday kitchen.Bleach and Rubbing Alcohol.Two Different Brand of Batteries.Potassium and water.Baking soda and vinegar.Mentos and Soda.

What is the most violent chemical reaction?

Cesium and water One of the most dangerous chemical reactions is a mixture of cesium with water, because when these two substances come into contact, there is an immediate explosion.

What are the 7 signs of a chemical reaction?

Seven Things That Indicate a Chemical Change Is OccurringGas Bubbles Appear. Gas bubbles appear after a chemical reaction has occurred and the mixture becomes saturated with gas. … Formation of a Precipitate. … Color Change. … Temperature Change. … Production of Light. … Volume Change. … Change in Smell or Taste.

Is Hot ice a chemical reaction?

D. Sodium acetate or hot ice is an amazing chemical you can prepare yourself from baking soda and vinegar. You can cool a solution of sodium acetate below its melting point and then cause the liquid to crystallize. The crystallization is an exothermic process, so the resulting ice is hot.

What are the 3 most important chemical reactions?

Combustion of methane (hydrocarbons)Photosynthesis.Synthesis of sulfuric acid.Equilibrium of carbonic acid and carbon dioxide gas.Biological formation of calcium carbonate.Rusting of iron.Production of hydrogen from the action of acid on metal.Oxidation of alcohol.More items…

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.

What are the evidence of chemical reaction?

Evidence of a chemical change Change of odor. Change of color (for example, silver to reddish-brown when iron rusts). Change in temperature or energy, such as the production (exothermic) or loss (endothermic) of heat. Change of composition – paper turning to ash when burned.

What are signs of chemical reaction?

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.

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.

Is cooking an egg a chemical reaction?

Cooking the egg is an example of a chemical change.

What are simple reactions?

Some examples of simple synthesis reactions include: hydrogen + oxygen —> water. iron + oxygen —> rust. … water + carbon dioxide + light —> glucose and oxygen (photosynthesis) sodium + chloride —> sodium chloride (table salt)
