Answer:
Specific heat is the amount of energy that must be added, in the form of heat, to one unit of mass of the substance in order to cause an increase of one unit in temperature.
Explanation:
Compound is a group of same molecules, Element is a group of same atoms and mixture is combination of two or more pure substances.
What are Molecules ?
Molecules are the combination of two or more different atoms combine in a fixed ratio.
Molecules can be independently founded.
Atoms are always founded in combined state and does not occurs independently except rare earth elements which belongs to 18th group of periodic table.
Chemicals are taken in compound state But they undergo chemical reaction individually in molecular level.
Hence, Compound is a group of same molecules, Element is a group of same atoms and mixture is combination of two or more pure substances.

All of them are a source of getting energy but solar and wind energy are a more beneficial way of producing the energy we need.
Answer:
A) high spin complex
B) low spin complex
Explanation:
A) VCI3(H20)3 is a high spin complex and this is because the complex has a weak field ligands all . this weak field ligands makes it impossible for pairing to take place
B) Fe(NH3)23 is a low spin complex and this is because the complex is made up of strong field ligands, this strong field ligands makes it possible for paring to take place
note : Ligands in which its donor atoms are ; Nitrogen,phosphorous or carbon are considered strong ligands
