Phenol reacts with dilute nitric acid at room temperature to give a mixture of 2-nitrophenol and 4-nitrophenol while with concentrated nitric acid, more nitro groups get substituted on the ring to give 2,4,6-trinitrophenol which is known as picric acid.
Answer:
72 ml-50 ml =22 ml is the volume of the object
Explanation:
The type of reaction that will occur with the given compounds is double-replacement where the components of one is replaced by that from another. This is,
K3PO4 + MgCl2 ----> Mg3(PO4)2 + KCl
Balancing the reactant and product sides,
2K3PO4 + 3MgCl2 ---> Mg3(PO4)2 + 6KCl
The line spectra of an atom offers conclusive evidence that electron energies are quantized.
Neils Bohr showed that electrons in an atom can absorb or emit energy when they move from one energy level to another. This principle is the basis upon which the spectra of atoms is built.
The true statements about the atomic spectra is;
- The line spectra of elements are evidence that electron energies are quantized
- Energy is emitted from atoms as they move from higher energy levels to lower energy levels
