A particle of two or more elements chemically combined.
What is a molecule?
A combination of two or more particles that are not chemically combined.
What is a mixture?
Fog is not a compound, but it is this.
It is a colloid of water and air.
The study of matter, motion, and forces.
What is physics?
The smallest unit in which an element can be divided and still maintain its properties.
What is an atom?
A combination of particles in which the particles are not uniformly distributed.
What is a heterogenous mixture?
A mixture in which the particles can be seen and will eventually settle. It blocks light.
What is a suspension?
The study of atoms, elements, compounds, and mixtures.
What is chemistry?
Two or more elements chemically combined.
What is a compound?
The process used to separate salt from water.
What is distillation?
The particles in this mixture can only be seen with the use of an electron microscope.
What is a colloid?
A building is 174 meters tall, which is equal to this in feet. (1 m=3.28 ft.)
What is 570.72 feet?
Anything that has mass and takes up space.
What is matter?
The process used to separate sand and water. It was also used during gold mining.
What is filtration?
This effect can only be found in colloids.
What is the Tyndall effect?
An example of a compound that is also a pure substance.
What is water?
The study of atoms and molecules, and how they interact.
What is chemistry/ What chemists want to learn.
A mixture in which the elements are not chemically combined, but are evenly distributed and uniform.
What is a homogenous mixture?
A colloid can be distinguished from a homogenous mixture through this.
What is indirect evidence?
Development of medicines, machinery, rapid communication devices, faster transportation, and space exploration.
