STAGE 1 - Basic Foundations of Chemistry

Two general properties of matter

Sublimation is involving the change from:

Hydrolysis & oxidation are physical properties.

Type of renewable energy obtained from organic matter such as wood, manure, or coal.

Tap water is a homogeneous mixture

Chemistry is the study of matter and its transformations

Aristotle promoted the theory of 4 elements (earth, air, water & fire)

Alloys such as bronze, steel, brass are homogeneus mixtures

What is the method used for separating mixtures such as blood?

Deposition is the transition from gas to solid

Distilled water is a compound.

They are the simplest form of matter. They are made of one type of atom.

It is the energy of motion without which nothing would move.

It is the energy due to its movement or rest. It depends on the masa and speed.

It represents transition from gas to liquid

It is the energy stored in food and substance.

Following examples are chemical changes.

Melting occurs when “A” turns into:

What is the method for separating mixtures showed in the picture?

Malleability and ductility are physical properties

It is a heterogeneous mixture with an opaque appearance; when left undisturbed, its dispersed phase settles.

Method used to separate the components of petroleum?

In a physical change:

Classify the changes.

What is the method for separating a mixture of oil and water if they are immiscible?

He established the law of mass conservation
