1. is anything that has mass and takes up space. A(n) 2. is a single kind of matter that is pure, having a specific makeup and specific properties. Every form of matter has two kinds of properties. A(n) 3. property can be observed without changing the substance into another substance. A(n) 4. property describes the ability of a substance to change into different substances.
The simplest substances, called 5., cannot be broken down into any other substances by physical or chemical means. A substance made of two or more elements chemically combined is a(n) 6.. A 7. consists of two or more substances that are in the same place but not chemically combined. You can see the different parts in a
8. mixture. But the substances in a
9. mixture are so evenly mixed that you can’t see the different parts.
The basic particle of an element is called a(n) 10.. Atoms can combine with other atoms. The force that holds two atoms together is called a(n) 11.. A group of atoms that are joined together by chemical bonds form a larger particle called a(n) 12..
There are many types of 13., the ability to do work or cause change. 14. energy is the total energy in all the particles of an object. 15. energy is the energy stored in the chemical bonds between atoms. 16. energy is a form of energy that travels through space as waves. 17. energy is the energy of electrically charged particles moving from one place to another.

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
