chemical reactions
Protein
Stars do not carry out a chemical reaction; they carry out a thermonuclear reaction. Instead of chemicals reactiing to form new compounds, hydrogen atoms fuse together to formm helium. This process releases far more energy than any chemical reaction.
Enzymes.
enzymes
Light usually provides enough energy for exchange of electrons and carry out the chemical reaction.
Practically all chemical compounds can react. Compounds that help chemical reactions are called catalysts.
Heat speeds up chemical reactions. As corrosion is a chemical reaction, copper pipes at a higher temperature will corrode faster
To carry out biochemical reactions enzymes are needed as catalyst.
-A chemical reaction is a process that changes, or transforms, one set of chemicals into another. An important scientific principle is that mass and energy are conserved during chemical transformations. This is also true for chemical reactions that occur in living organisms. some chemical reactions occur slowly, such as the combination of iron and oxygen to form an iron oxide(rust). Other reactions occur quickly. The elements or compounds that enter into a chemical reaction are know as reactants. The elements or compounds pruduced by a chemical reaction are known as products. Chemical reactions always involve changes in the chemicdal bonds that join atoms in compounds. -Chemical reactions that occurs in your body involves carbon dioxide. Your cells constantly profuce carbon dioxide as a normal part of their activity. Carbon dioxide is carried to you lungs through the bloodstream, and then is eliminated as you exhale. Carbon dioxide is not very soluble in water. The bloodstream could not possibly dissolve enough carbon dioxide to carry it away from your tissues were it not fro chemical reaction. As it enters the blood, carbon dioxide reacts with water to produce a highly coluble compind called carbonic acid, H2CO3. CO2 + H2O ---> H2CO3 The reaction shown above enables the bloodstream to carry carbon diocide to the lungs. In the lungs, the reaction is reversed. H2CO3 ---> CO2 + H2O This reverse reaction produces carbon dioxide gas, which is released as you exhale.
yes! it goes thru your digestive system. The energy from our food is released by chemical reaction inside us and the energy transfer allows us to carry out all the body's normal processes.
They each carry an axe.
An electron or an aluminum ion carry a negative charge.
