Gas
Kinetic energy is the energy an object has due to its motion. The faster particles move, the more kinetic energy they have. Solid objects have the least kinetic energy because their particles vibrate in place. Gases have the most kinetic energy because their particles move very quickly.
Elements. Elements cannot be further separated as they are the most basic substances.
The new combination is called a mixture.
In mixtures, since the substances are not chemically combined together, they still remain their own physical and chemical properties, and can be separated by simple physical methods such as filtration or distillation.
On the other hand, if the two or more substances are combined where they get new properties, the new combination will be called a compound. They cannot be separated by physical methods, but chemical methods such as heating or electrolysis.
Answer:
Chlorine's (Cl) atomic mass if 17.
