Examples of chemical changes in the nature?
Examples of chemical changes in nature include wood burning in a forest fire, photosynthesis, the formation of sulfuric acid in volcanic vents, and the fixing of nitrogen in lightning bolts and bacteria.
Is it wrong to say a chemical change is irreversible while physical change is reversible?
Simplistically speaking, the statement is true - not wrong/false. For example, one physical change is to fold paper. After the paper is folded, you can rather effectively unfold it and return it to its original condition. One chemical change is to burn something. After paper is burned, the ashes cannot be "unbunrt" back into paper. However, some chemical changes are reversible. For example, photosynthesis is a chemical change in which water, carbon dioxide, and energy are turned into oxygen and sugars. Respiration is a chemical process in which oxygen and sugars are converted back into water, carbon dioxide, and energy. However, the process of respiration is much more complex than photosynthesis and is not the "reverse" of it, i.e. respiration is non un-photosynthesis.
What process changes light energy into chemical energy in an ecosystem?
The process that changes light energy into chemical energy in an ecosystem is photosynthesis. During photosynthesis, plants and other photosynthetic organisms use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. This glucose serves as an energy source for the organism and other organisms in the ecosystem.
What are some kinds of chemical changes that release energy?
Some examples of chemical changes that release energy include combustion reactions, oxidation reactions, and certain types of nuclear reactions. These reactions typically involve the breaking of chemical bonds and the formation of new, more stable bonds, resulting in the release of energy in the form of heat or light.
What is the differnce between physical and chemical change?
Physical changes are changes in appearance, state, or form of matter without altering its chemical composition. Chemical changes involve the formation of new substances with different chemical properties. Examples of physical changes include melting ice or tearing paper, while examples of chemical changes include rusting of iron or burning wood.
What are 10 examples of chemical changes?
Fire extinguishers fire fireworks cooking electrocution decomposing photosynthesis cellular respiration contamination creating salt
What are two examples of chemical changes?
1) a nail rusting 2) photosynthesis
What are the chemical and physical changes of photosynthesis?
There are no physical changes. there are only chemical changes.
What are some examples of chemical changes found in animals?
Examples of chemical changes in animals include the digestion of food in the stomach, the conversion of nutrients into energy through cellular respiration, and the synthesis of hormones and enzymes. These chemical processes are vital for the survival and functioning of animals.
Examples of chemical changes in the nature?
Examples of chemical changes in nature include wood burning in a forest fire, photosynthesis, the formation of sulfuric acid in volcanic vents, and the fixing of nitrogen in lightning bolts and bacteria.
Why is Photosynthesis is chemical changes?
photosynthesis is a chemical change because the sunlight that gos into the plant turns into nutrients that eventually turn into a liquid
Examples of chemical change that occurring around us or within us?
Examples of chemical changes that occur around us include burning wood (combustion), rusting of iron (oxidation), and cooking food (chemical reactions in the ingredients). Examples of chemical changes that occur within us include digestion of food (enzymatic reactions), respiration (breaking down glucose for energy), and metabolism of medications in our bodies.
A chemical reaction that occurs in plants that changes light energy into chemical energy is?
photosynthesis
What is the chemical process that changes light energy to chemical energy?
You think probable to photosynthesis.
What process changes light energy into chemical energy?
Photosynthesis
Is the energy involved in photosynthesis and cellular respiration recycled?
Solar energy is transformed into other types of energy once it is in the biological cycle. The only way it may be released is as heat energy into space. Sunlight powers photosynthesis, and the ultimate function of this stored chemical energy is as mechanical energy and waste heat.The energy that plants store may be used in cellular respiration, but never goes back to the plant. The physical materials are mostly recycled (water, carbon dioxide, and trace nutrients) because cellular respiration undoes the chemical changes of photosynthesis.
What chemical changes occur during the digestive process?
Cellular respiration
