Answer: There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.
Answer: Graphite and Diamond are different because they have different structures. Both have Giant Covalent Structures resulting in very high melting temperatures.
Explanation: each carbon atom in Diamond has 4 covalent bonds with other Carbons, making it extremely strong and hard.
The balanced equation is as below
2 N₂O₃ → 2N₂ + 3O₂
<u><em> Explanation</em></u>
According to the law of mass conservation the number of atoms in reactants side must be equal the to the number of atoms in products side.
Therefore the balanced reaction above is balanced since the number of atoms in reactants side are equal to number of atoms in products side.
For there 4 atoms of N in reactants side and 4 in products side.
