Do you need to know how electromagnetic waves can be produced by accelerated charge and other important aspects of high school chemistry? This free online course provides you with an in-depth understanding of the rules of identifying significant figures. It is important to understand the process of data collection by making adding subtracting and dividing the measurements. Before working with scientific notations it is essential to know how the decimal point can be moved directly after the first significant figure. This course takes you through the metric system dimensional analysis and the different physical states of matter. Do you know why substances are separated and why the number of atoms in a compound is based on the chemical formula? This course will teach you the crucial procedures you need to know.If you want to understand the concept of heterogeneous and homogeneous mixtures including the types of pure substances then sign up today. Once you have finished the modules you should be able to explain the properties of metals non-metals metalloids and various types of energy associated with matter. You will also have a better understanding of nuclei electrons neutrons and protons. Do you know it is possible to determine the number of particles an atom contains?
