Answer 1

Answer:

Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances. Compounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.

Answer 2

Explanation:

Assumptions of Werner’s Theory

Assumptions of Werner’s TheoryThe important postulates of Werner’s theory are:

Assumptions of Werner’s TheoryThe important postulates of Werner’s theory are:The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and secondary valency.

Assumptions of Werner’s TheoryThe important postulates of Werner’s theory are:The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and secondary valency.The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number.

Assumptions of Werner’s TheoryThe important postulates of Werner’s theory are:The central metal or the metal atoms in coordination compounds show two types of valency. They are the primary and secondary valency.The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number.The number of secondary valences is fixed for every metal atom. It means that the coordination number is fixed.

They are the primary and secondary valency.The primary valency relates to the oxidation state and the secondary valency relates to the coordinate number.The number of secondary valences is fixed for every metal atom. It means that the coordination number is fixed.The metal atom works towards satisfying both its primary and secondary valencies. A negative ion satisfies the primary valency. On the other hand, a negative ion or neutral molecules satisfy secondary valencies.
