Which property of physical changes explains why matter is conserved in a physical change?
Mass is always conserved in a chemical change, which process involves involves the rearrangement of atoms and molecules. Of course most physical changes also conserve mass: when $10*g$ of liquid...

It is said chemical and physical properties are closely linked. Why does a chemical change also cause a change in physical properties?
Different combinations of atoms have different physical properties. For instance, when iron rusts, its melting point lowers.

The nonmetals are found to the right of the staircase line on the modern periodic table. What are the physical characteristics of the non-metals?
The solid non metals are amorphous. Unlike metals the non metal solid do not usually form a regular crystal shape. The solid non metals are generally soft and easily broken...

What type of bond is formed when nonmetals combine with other nonmetals?
Nonmetals have relatively high electronegativity, so both atoms in the bond want to keep the electrons that are being shared between them. This creates a covalent bond. If one...
