Water is a pure substance because it is not refined like the other materials. Hope this helps!!!
Answer:
Ionic or Electrovalent Bonding
Explanation:
There are primarily two categories of bonding between chemical entities. We have; Ionic Bonding and Covalent Bonding.
Ionic bonding or electrovalent bonding is the complete transfer of valence electron(s) between atoms. There is the transfer of electron from typically a metal to a non metal.
Covalent Bonding however involves the sharing of electrons between atoms. Depending on whuch atoms provide the electrons, it can be ordinary covalent oor coordinate covelent bond.
The subatomic particles that identifies an element and also represents its atomic number would be A. The number of protons.
1,2-methylcyclohexane, 1,3-methylcyclohexane, 1,4-methylcyclohexane
A displacement reaction (also known as a replacement reaction) is when one element is replaced by another compound. Ex) Fe+CuSO4=FeSO+Cu
