C is the answer because that is an actual chemical change where the sulfur and iron are not separate from each other anymore
The answer would be letter A
Answer:
A. The kinetic molecular theory relates the properties of a state of matter to the motion of its molecules.
Explanation:
The higher the kinetic energy of the molecules, the faster its movement will be. The state of a matter will depend on how fast the molecules move. When the molecules barely move, it will be packed tightly and its state will be solid. If the molecules kinetic energy rises, eventually they start moving around and the state will be liquid. If the kinetic energy rises further, the molecule will expand and changed into gas form.
Density of liquid= 
.
so, density of liquid= 
= 1.2 gm/cm³.
