This guide explores the fundamental concepts of matter, detailing the differences between pure substances and mixtures. It examines whether mixtures can be separated by physical means, how pure substances can be decomposed through ordinary chemical methods, and identifies whether compositions are uniform or not. We categorize matter into elements, compounds, homogeneous, and heterogeneous mixtures, providing examples such as water, air, stainless steel, granite, and more. Gain insight into the building blocks of matter.
