Answer : According to the definition of law of refelection "<em>It is </em><span><em>the principle in which, when a ray of light or radar or pulse, is shined on a smooth surface it is reflected back from the smooth surface and the angle of reflection will be equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface at the point of incidence all will lie in the same plane."
</em>So we can define angle of incidence as - The angle which is formed between the incident ray and the smooth surface of substrate is called angle of incidence and the incident ray will be always intersecting at the point of normal with the reflected ray. So the normal is an imaginary line which is perpendicular to the smooth surface of the substrate which bisects the ray of incidence and forms the angle of incidence also it bisects the ray of reflection and forms angle of reflection.</span>
by looking at the periodic table I think Florian is a gas because it's important like in the bottom

Answer:
Explanation:
Physical properties and physical change:
Physical properties are the properties of substance that do not involve the change in to another matter while the process through which change is happen is called physical change.
For example,
Melting point is physical property and the process "melting" is called physical change.
Freezing point is physical property and the process "freezing" is called physical change.
Chemical property and chemical change:
Chemical property is the ability of substance to change into another substance while the process through through which it is happen is called chemical change or chemical reaction.
For example:
The chemical property of iron is to react with oxygen and form rust. This process or chemical change is called corrosion. So corrosion is chemical change.
Hydrocarbon react with oxygen and form water and carbon dioxide. It is the chemical property. While the process is called combustion so combustion is a chemical change.
