two types are movement and reproduction,
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
The sum total of all the chemical reactions occurring in the body are called the metabolism.
forms
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Vinger and bicarb!!
sodium bohyroxide
Synthesis, decomposition, combustion, and oxidation are some examples of chemical changes (reactions) of matter.
Chemical reactions are sources of pollution. Some examples of these reactions are: combustion, burning of fossil fuels and acid rain.
Fireworks and wood burning are good examples of fast chemical reactions =]
only nuclear reactionsChemical reactions that release free energy are called exergonic reactions. Fire and cellular respiration are examples of exergonic reactions.
The mixed geo-chemical processes refers to the various earth processes and those that are related to Chemistry. Photosynthesis and respiration are some examples of the geo-chemical processes.
Reactions that are not chemical reactions are physical reactions. These reactions involve a change in only the physical state of an element, not its chemical properties. Thus, physical changes include freezing, condensation, sublimation, hammering a metal into a sheet, cutting sodium metal, etc.
