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.
Answer:
A. Sugar
Explanation:
Sugar dissolves in water because of its molecular structure (C6H12O6), as the sugar is put in the water, energy is released and the polarity of the water breaks apart the molecules. However, the molecules can be obtained back by evaporating the water.
Honestly, you can look at the notes you took and even look down some things in google to help u solve ur answer
Answer:
- blue-black PHYSICAL PROPERTY
- crystalline PHYSICAL PROPERTY
- solid PHYSICAL PROPERTY
- sublimes to a violet-colored gas PHYSICAL PROPERTY
- reacts with aluminum and many other metals CHEMICAL PROPERTY
Explanation:
Chemical properties are visible through chemical reactions, in which the chemical identity changes to form new substances. On the other hand, physical properties are evident without a change in the identity of a substance.
