Define chemistry. (1)
The study of matter.
Define matter. (1)
Anything that has mass and takes up space.
List four points of the Particle Theory of Matter.
- All matter is made up of small particles known as atoms.
- Particles of matter are constantly in motion.
- Particles of matter attract each other.
- Particles of matter have spaces between them.
Define substance.
Matter that consists of only one type of particle.
Define element. (1)
A substance in which the particles are atoms.
Define compound. (1)
Substances formed by chemically combining 2 or more elements.
Define mixture. (1)
Matter that consists of two or more types of particles that are physically mixed together.
Define homogeneous mixture. (1)
A mixture consisting of true particles (atoms or molecules).
List examples of homogeneous mixtures. (4)
- Salt water
- Sugar water
- Vinegar
- Vodka
Define solution. (1)
A type of homogeneous mixture in which one substance is dissolved in another.
In a solution, the ______ is dissolved into the ______.
In a solution, the solute is dissolved into the solvent.
Define alloy. (1)
A solid dissolved into a solid.
Define / describe heterogeneous mixtures. (2)
- A mixture containing things that are not true particles.
- Parts will be visible because particles are bigger.
Define / describe suspensions. (2)
- A heterogeneous mixture in which the particles are dispersed throughout * the medium.
The particles will settle through gravity.
Define / describe colloids. (1)
A heterogeneous mixture in which the particles are smaller than a suspension’s, but still bigger than true particles.
