What will I learn?
The online chemical stoichiometry course (in its free or paid mode), Chemical Reactions and Stoichiometric Calculations from the Universitat Politècnica de València, will teach you the concepts and techniques to solve chemistry problems related to chemical reactions and the amounts of reactants and products.
This course is aimed at anyone who wants to acquire or improve their knowledge of basic chemistry, whether for personal interest or academic or professional needs. It is recommended to have some notions of general chemistry and algebra. The course has a rigorous and didactic approach, which combines clear and detailed explanations with examples and activities that will help you consolidate your learning. The course also offers additional resources, such as readings, videos, and links of interest, which you can consult to expand your knowledge and delve into the topics that interest you most.
This course is available on the edX platform, one of the most prestigious in the world in online education, founded by MIT and Harvard University. It can be taken totally for free or by paying a small fee.
Contents of the online chemical stoichiometry course, Chemical Reactions and Stoichiometric Calculations
In the course, you will be able to access the following contents:
- Chemical reactions. You will learn to define and classify chemical reactions according to their type and mechanism, to recognize the reactants and products of a reaction, and to write and interpret the chemical equations that represent them.
- Balancing chemical equations. You will learn to apply the principle of conservation of mass to balance chemical equations, that is, to adjust the stoichiometric coefficients that indicate the proportion of reactants and products in a reaction. You will also learn to use different methods to balance chemical equations, such as the trial-and-error method, the algebraic method, or the ion-electron method.
- Stoichiometric calculations. You will learn to perform stoichiometric calculations, which are those that allow determining the amounts of reactants and products involved in a chemical reaction, expressed in units of mass, volume, moles, or number of particles. You will also learn to use the laws of definite and multiple proportions, the law of conservation of mass, the concept of mole, and Avogadro’s constant to solve these calculations.
- Yield and purity of chemical reactions. You will learn to define and calculate the yield and purity of chemical reactions, which are two parameters that indicate the efficiency and quality of a reaction. You will also learn about the factors that influence the yield and purity of reactions, such as the amount of reactants, the excess or defect of any of them, the reaction rate, temperature and pressure conditions, or the presence of impurities or side reactions.
Free or paid chemical stoichiometry course
The course has two modalities: free and paid. The free chemical stoichiometry course mode allows you to access all the course content, including videos, readings, exercises, and discussion forums.
The paid modality also offers you the possibility of obtaining a verified certificate from edX, which accredits your participation and completion of the course. This certificate can be of great value to your curriculum vitae, as it demonstrates your interest and competence in the quantitative study of chemical reactions. In addition, by paying for the course, you will be contributing to the Universitat Politècnica de València and edX being able to continue offering quality and accessible courses for everyone. If you want to know more about the cost and benefits of this modality, I invite you to visit the course page on edX, where you will find all the information you need.
In conclusion, the online chemical stoichiometry course (in its free or paid mode), Chemical Reactions and Stoichiometric Calculations, is a course that gives you an excellent opportunity to learn or review the concepts and techniques for balancing chemical equations and performing stoichiometric calculations, and for applying them to the resolution of chemistry problems. Do not hesitate any longer and register for the course now. You won’t regret it!
