Alison is one of the world’s largest free
learning platforms for education and skills training. It is a for-profit social
enterprise dedicated to making it possible for anyone, to study anything,
anywhere, at any time, for free online, at any subject level. Through our
mission we are a catalyst for positive social change, creating opportunity,
prosperity, and equality for everyone. Alison was founded in Galway, Ireland, in 2007
and has grown organically to become a major force in free online education and
skills training. Today, with more than 13 million learners in 195 countries,
Alison is changing how the world learns and up-skills. They are committed to equality and access to
education and skills training irrespective of gender, geography, economic
status or any other barriers that can so often stunt potential. So they offer a
range of free courses that meet the many diverse needs of our learners. The UN
declared in Article 26 of the 1946 Declaration of Human Rights that “Education
shall be free…”. This statement will always inspire us. Alison was founded by Alison CEO, Mike Feerick. Mike is a businessman, but one with a
difference. He believes in social impact, and that you can build a financially
successful business focused on meeting a huge global social need, making
education and skills training more accessible for everyone. He invites anyone
who believes that too, to support the Alison mission.
Alison is free of charge to you. But it’s still
a business – albeit a socially-focused one. We are a social enterprise making
our money through advertising, merchandise, and the sale of Certificates and
Diplomas, should a graduate choose to buy one. |
This course will first discuss the periodic table and the groups of elements. You will study chemistry symbols, atoms and molecules, elements, and compounds. You will also cover ions and particles, and study the three states of matter: liquids, gases, and solids. You will look into mixtures, and discuss the two types of corrosive substances: acids and bases. In addition, this course will discuss PH scales, PH meters, and acid-base indicators.
Mixtures can be separated using different techniques. This course will discuss chromatography (which is used to separate mixtures of substances into their components), decanting (which is the separation of liquids from solids by gradual pouring), dissolving, solidification, and precipitation. You will also look into evaporation, distillation which purifies a liquid by heating or cooling, and filtration which separates solids from liquids using a medium. You will also study sublimation which is the transition of a substance directly from the solid to the gas phase.
Chemistry is also known as the central science because it joins together biology and medicine, physics and mathematics, and the earth and environmental sciences. By the end of this course, you will have gained a deeper understanding of the behavior of atoms, molecules, and ions, all of which determines the very world we live in. So, check out this course today and start gaining a clearer understanding of the fundamentals of chemistry, all for free.
