Objective: At the end of the activity, you should be able to distinguish mixtures from compounds according to its composition and properties. Directions: You just discovered the properties of mixtures and substances. On this activity, your task is to distinguish mixtures from compounds (classification of a substance) based on their composition and properties. You may refer to your readings from Brief Introduction.

1. Composition
Mixtures are heterogeneous forms of matter. Mixtures are composed of variable proportions of molecules and atoms. Compounds are homogeneous forms of matter. Their constituent elements (atoms and/or ions) are always present in fixed proportions
2. Process of Combination
A mixture is a combination of two or more substances in any proportions. The substances in a mixture do not combine chemically, so they retain their physical properties. A homogeneous mixture has the same composition throughout. A heterogeneous mixture varies in its composition.
A combination reaction, also known as a synthesis reaction in chemistry, is when two or more substances, or reactants, combine with each other to form a new product. The product will always be a compound.
