CHEMICAL REACTIONS

In a chemical reaction, molecules of one substance divide and bond with molecules of another substance to produce different compounds (combination of molecules). Many chemical reactions are irreversible changes. You can not turn freshly baked cakes into raw materials. Some chemical reactions are reversed and the original material may be reformed. All of these can be changed

Iron and magnesium in fireworks react with oxygen when burning and make ash and smoke. They also release spectacular heat, light and noise. Chemical change creates new materials. Also, because chemical bonds are destroyed and manufactured, it usually releases or absorbs energy such as heat and light.

When iron rusts, it reacts with water and oxygen in the air to produce new compounds called iron oxide (rust). As with each chemical reaction, there is no mass loss or increase. The same atom as the original material is in the new material, but the place is different. Weighing iron oxide with this rusty ship will weigh the same amount as the original iron and oxygen.

Melt ice candy is not a chemical change but an example of a physical change. Liquid ice candy is not a new material, it is simply a different form of old material. Physical changes do not create new substances nor destroy or create chemical bonds. Melting, freezing, tearing, bending and breaking are physical changes that alter the appearance of matter without changing its chemical nature.

Many chemical reactions are irreversible changes. That is, they are permanent changes that can not be undone. You can no longer make new materials. Rust is an irreversible change. However, when rust is mixed with the magnesium powder, another chemical reaction occurs and iron may be extracted from the rust.

Decomposition (rot) Food is an irreversible reaction. Microorganisms known as microorganisms eat food and convert it to other substances, including nitrogen compounds and carbon dioxide. It is impossible to regenerate fresh food from rotten food. This process is called decomposition, as complex compounds are divided into simpler compounds.

Several chemical reactions can be reversed - the original material can be recast from the new material. These reactions are called reversible changes. They have a forward reaction and a backward reaction. These two reactions actually occur simultaneously, but depending on the conditions one reaction becomes stronger than the other.

The word "reaction" is good. Then, how about "chemical reaction"? Although chemical reactions are allergic reactions, chemical reactions are different from common allergic reactions, but they are easily blown away because of allergies. I would like to know if it is important that you think that it is important when you listen to the word when you hear that word. Chemical reactions are totally different as it may take a long time to identify allergic chemicals. You do not want to avoid what you do not want to avoid. Even knowing what to avoid, it is impossible to do this if large companies are using legitimate loopholes to hide toxic chemicals on their daily products.

It is various initial responses that our situation is confused at first or looks strange. You must remember that we are chemically reacting to several different chemicals at the same time. We have reached the toxicity threshold of different chemicals at different times. Then as time went on we began to react differently to multiple chemicals at the same time. As time goes by, we will be a similar list of symptoms (response). The only way to stop a chemical reaction is not to use it. In our case, this means uniform. As long as Americans do not recall new uniforms, our number will increase and our number of diseases will continue to worsen. Even if you are wearing old uniforms or fake uniforms, the problem will not be solved. Inhalation of chemical substances is also carried out. When my colleague keeps on poisonous uniforms, it does not matter whether I wear an old uniform or a fake uniform. Proximity response is genuine
