Rutherford in his model of an atom proposed that in an atom positive charge is concentrated in the center of an atom with he named nucleus and along with that also told that whole of an atom is also concentrated in the nucleus of an atom.
Bohr → Electron energy levels
Bohr in his structure of atom explained that electrons revolve around the nucleus in fixed orbit or shell or energy levels.These energy levels are stable and are stationary along with different energy value.
Schrodinger → Electron cloud and orbitals
Schrodinger proposed the mechanic model of atom in which he defined the location of electrons inside an atom by electron cloud in 3-d space.To define their location he introduced concept of quantum number.
A chemical change can cause an odor, however a physical change cannot, and the use of thermal energy will only make an object colder, not give it an odor.
Explanation:Saponification reaction is a reaction in which hydrolysis of fats takes place under basic conditions giving glycerol and a salt of corresponding fatty acid.
We are given a Fatty acid called as Trimyristin.
Its reaction with KOH leads to the formation of soap and is given by the equation:
The condensed structural formula for the equation is given in the image attached.
A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. ... In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
