Chemistry - Introduction to Advanced Learning Path
As the science field continues to grow, there is an increasing demand for individuals with scientific knowledge. As one of the three main science subjects, a basic understanding of chemistry is a must for anyone looking to work in the science industry. Studying the Alison learning path in chemistry will help you better understand the main elements of the subject, and will help you to excel in any scientific area of work. This learning path will also be beneficial to any student who wants to better understand the fundamentals of the subject and boost their chemistry grades. The Alison chemistry learning path is a series of courses that will help you to build and improve on your chemistry knowledge, from the very basics to more advanced areas of study. You will learn about key areas of chemistry, such as the periodic table and its elements, molecules, gases, matter, and substances. For example, you will be able to break each element down to its relevant atoms and determine how the structures of these atoms influence the element's place on the periodic table. You will also learn about chemical equations, such as Avogadro’s number or the Mole which are used to convert between atomic mass and grams. You will also learn about the effects which heat can have upon gases and substances.

Fundamentals of Chemistry
This free online chemistry course will help you get a good grasp of the periodic table of elements and symbols. It will also familiarize you with ions and particles, which are a group of atoms or molecules that carry a positive or negative electric charge and a tiny portion of matter. You will also cover the three states of matter, namely gases, liquids, and solids. The course will then tackle the subject of mixtures, acids, bases, and acid-base indicators, as well as PH scale and meters.
Next you will study chromatography, which is a method of separating many different kinds of chemical mixtures. The course will discuss solidification, dissolution, and decanting (the process where a mixture is allowed to settle and separate by gravity). You will then learn about precipitation or the emergence of an insoluble solid from a solution, as well as evaporation and distillation, which is the action of purifying a liquid. The course then covers filtration and sublimation, which is the transition of a substance directly from the solid to the gas phase.
Chemistry is a part of our everyday lives, whether we realise it or not. An understanding of basic chemistry concepts can open up avenues in a really wide range of careers, as well as help us understand the world we live, sleep, and eat in. This Fundamentals of Chemistry course is ideal as a study aid for secondary school students or anyone interested in learning the basics of chemistry. Check out the course today, and start learning some fascinating knowledge about the matter all around you.3-4 Hours50 Points
Chemistry - Atoms, Elements and the Periodic Table
Two fundamental aspects of chemistry are, firstly, the structure of the atom and the role of the subatomic particles neutrons, protons and electrons, and, secondly, the atomic structure of the known elements that make up everything and how their place in the Periodic table of the elements determines their chemical properties. This free online course will give learners a comprehensive knowledge and understanding of these two core building blocks within chemistry. The course starts by examining the structure of the atom and subatomic particles, and then discusses the elements, and breaks them down into their subatomic structure of protons, neutrons and electrons. You will learn how the structure of each element determines its place in the Periodic table and its chemical properties. This course will be of great interest to all students who wish to pursue a career in any of the sciences such as chemistry, physics, biology or geology, or the individual learner who simply wants to learn and understand what the world around us is made up of.

Chemistry - Molecules and their Composition
A molecule is a group of two or more atoms that bind together using chemical bonds. They may be from one or multiple elements and it is the ratio, or mass composition, of each molecule that gives the molecular compound its chemical characteristics. In this free online science course, you will learn about molecules and how they are composed of various elements, in mass, atoms and ratios. The course introduces the student to Avogadro’s number or the Mole, which is used to convert between atomic mass and grams, so that you will be able to work out ratios and weights of molecules. You will also learn how to balance chemical equations, and by balancing the reactants within equations, get viable chemical reactions. This branch of chemistry is known as Stoichiometry. The course will be of great interest to all students who wish to pursue a career in any of the sciences such as chemistry, physics, biology or geology, or the individual learner who simply wants to learn and understand how atoms form the molecules which make up all the material surrounding us.

Chemistry - Gases and Their Properties
Gases behave differently from either solids or liquids, so there are different methods for understanding their behaviour. Having neither fixed volume nor shape gases are moulded entirely by the container in which they are held and from this it is possible to measure their behaviour by measuring properties such as pressure, volume, temperature and number of molecules. This chemistry course will introduce the concept of the ideal gas and the ideal gas law which is a good indicator of the behaviour of gases under many different conditions. The various components in the ideal gas law are explained in clear terms and you will see that by using equations you will understand how the impact of a change to one property, for example temperature, will impact on the other properties. Where there are multiple gases in a container you will be shown how to work out their partial pressure relative to the total pressure. This chemistry course will be of great interest to all students who wish to pursue a career in any of the sciences such as chemistry, physics, biology or geology, and to the individual learner who simply wants to learn and understand how gases behave.1-2 Hour50 Points
Chemistry - States of Matter
Matter exists in four states - solid, liquid, gas and plasma and it will change state depending on the temperature and pressure applied to the matter.
In this chemistry course about states of matter you will learn about the characteristics of each of the four states and the amount of energy that can be added to or taken from a substance before it starts to change state.
As all substances change state at different temperatures and pressures you will learn how to use phase change diagrams to plot the energy and pressure levels, the triple point, critical temperature, boiling and melting points associated with different substances. You will also learn in a step by step manner how to calculate the change in energy needed to move a substance along the state of matter spectrum.
This chemistry course will be of great interest to all students who wish to pursue a career in any of the sciences such as chemistry, physics, biology or geology, or the individual learner who simply wants to learn and understand what is happening when matter changes from solid to liquid to gas.1-2 Hour50 Points
Chemistry - The Nature of Substances
The amount of energy required to change the state of a substance depends on how strong or weak the bonds between the molecules are. For substances with strong bonds at standard temperature and pressure, like diamonds, it is extremely difficult to separate the molecules, whereas substances with weak bonds, like helium, remain in a gaseous form and do not condense into liquid or solid states. In this free online chemistry course you learn more about factors that affect the chemical nature of substances. You will learn why substances changing state can also be affected by mixing substances together. The course explains about using water as a solvent and mixing in different substances to see the effect on the boiling and melting points of the solution. This is followed by step by step examples of working out what the change in boiling or melting point will be based on the amount of solute added. This chemistry course will be of great interest to all students who wish to pursue a career in any of the sciences such as chemistry, physics, biology or geology, or the individual learner who simply wants to learn more about factors that affect the chemical nature of substances.1-2 Hour50 Points
