That is a physical change. The is no chemical change that takes place when you sharpen your pencil in a standard manner. I suppose if you sharpen it extremely fast, you could catch the pencil on fire, which would then be a chemical change.
I believe it takes place in the Nucleous
It takes place in the year 1920.
It's the chemical breakdown of food into simpler compounds. Proteins are broken down to amino acids, carbohydrates are broken down to simple sugars, and fats are broken down to fatty acids and glycerol. Chemical digestion does begin in the mouth. Salivary amylase starts hydrolyzing starch the second you put in into your mouth. BUT, the vast majority of chemical digestion takes place in the duodenum and jejunum portions of the small intestine.
The conversion of solar energy to chemical energy takes place during photosynthesis. This is done by the chloroplasts in plants as they convert water and carbon dioxide into glucose. Chloroplasts
Monkey brins drink soda
The valence electrons are the part that takes place in a chemical reaction.
chemical reaction takes place in rancidity
These initial substances are the reactants.

Respiration takes place in every living cell will exceptions to red blood cells. Its a chemical reaction which produces energy from glucose and oxygen and makes carbon dioxide and water as its bi products.
Chemical reactions take place in various cell organelles. For example, in mitochondria, reactions like cellular respiration occur to produce energy. In the nucleus, reactions like DNA replication and transcription occur. And in the cytoplasm, reactions like protein synthesis take place.
When a chemical reaction takes place, the compound formed is called the product. The product is the end result of the chemical reaction, typically formed from the reactants that underwent a rearrangement of atoms.

Rusting is an oxydation reaction.
Respiration is considered as exothermic reaction because during the process,oxidation of glucose takes place which generates large amount of heat energy.
