Answer:
The coordination sphere of a complex consists of <u><em>the central metal ion and the ligands bonded to it.</em></u>
Explanation:
The Coordination Compounds are sets of a central metal ion attached to a group of molecules or ions that surround it. They are also called metal complexes or simply complexes. Then they are compounds that have a central atom surrounded by a group of molecules or ions, the latter called ligands.
The central atom must have empty orbitals capable of accepting pairs of electrons, with the transition metals being the ones with the greatest tendency. Because of this, they can act as Lewis acids (electron pair acceptors). The ligands have unshared electron pairs, then acting as Lewis bases (electron pair donors).
When forming a complex, it is said that the ligands coordinate to the metal and the central metal and the ligands attached to it constitute the coordination sphere of the complex.
Finally, <u><em>the coordination sphere of a complex consists of the central metal ion and the ligands bonded to it.</em></u>
Answer:
a what is the HCO3"/CO2 ratio
Answer:
D.) The higher vapor pressure of acetone results in more rapid evaporation and heat loss
Explanation:
Acetone being liquid with very low boiling point and hence can be easily be converted to gaseous state .
And ,
Therefore have higher vapour pressure and as liquid gets converted to gas , the process of evaporation takes place and leads to loss of heat .
Hence , from the given options , the most appropriate option according to given statement of the question is ( d ) .
Lead chromate is a precipitate that is formed on the reaction of lead nitrate with sodium chromate. The best method to separate this precipitate from the solution is filtration.
- A precipitate can be defined as an insoluble solid formed in a chemical reaction. It appears as a cloudy and resulted after a reaction.
- The lead chromate is yellow colored precipitate that forms after the reaction of lead nitrate with sodium chromate.
- The process of separation of insoluble solids from the liquids by the use of filters is known as filtration. Insoluble solids are also called as precipitates these precipitates are formed in a chemical reaction.
- Filtration will help in separation of insoluble solid yellow colored lead chromate precipitate from the solution using a porous material or filter that selectively inhibits the passage of solid precipitate material and allows the solution to pass through it.
