<u>Answer:</u> The chemical formula for this complex is or
<u>Explanation:</u>
2,2'-Bypridine is a bidentate chelating ligand which forms complex with many transition metals. Its chemical formula is
Bidentate ligands are the ligands which donate two pairs of electrons to the metal atom.
This complex contains two spheres: Primary sphere and secondary sphere
Primary sphere is the sphere which satisfies the primary valency of the metal and the coordination sphere satisfies the secondary valency of the metal known as secondary sphere.
Chlorine is satisfying the primary valency of the metal and bipyridyl is satisfying the secondary valency of the metal.
The chemical formula for this complex is or

Answer: metal and carbonate
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydrogen ions
in water.
An acid is represented as :
1. When metal is treated with an acid such as , if the metal is more reactive than hydrogen displaces hydrogen from its salt solution and thus produce zinc chloride and hydrogen gas.
2. When carbonates are treated with acid, double displacement takes place ad carbon dioxide is released as a gas.
