The chemical formula of oxalic is 
When oxalic acid reacts with water, first, oxalic acid removes one proton and results in the formation of mono acids.
After that, in second step, oxalic acid in aqueous solution removes another proton which shows it is a polyprotic acid.
The chemical equations are: (the reactions occurs in two steps due to presence to hydrogen atoms).
When one proton is removed:
When another proton is removed:
The dissociation of oxalic acid in water in shown in the image.
Answer:
1. Molecular solids are usually excellent conductors of electric current.
Explanation:
Molecular solids are actually insulators (prevent electricity).
Answer:
<h2>
Iron and Lithium are the two substances which are held by metallic bond.</h2>
Explanation:
- The metallic bond is a kind of chemical bond between positively charged atom and also the sharing of the free electrons among those positively charged ions.
- The Metallic bond elements have higher melting and boiling point and they are also called as the chemical atom between metal atoms.
- In Metallic bonding the outer shell electrons are loosely coupled and their adjacent atoms can overlap and they are free to move through the lattices.
The following are some of the characteristics of elements which have Metallic Bonding :
- Opacity
- Strength
- Thermal and Electrical resistivity
- Conductivity
- Malleability and Ductility
- Luster
