CARBONATES - SUBSTANCES THAT ALWAYS APPEAR IN ENEM Carbonates: Complete Review for ENEM Welcome to our channel! This video is a complete study on carbonates, preparing you in a solid and comprehensive way to face ENEM. We will talk about: calcium carbonate (limestone or marble), sodium bicarbonate and lime, providing an in-depth view of their importance in chemistry and beyond. Calcium Carbonate (CaCO3): Discover the presence of this mineral in rocks such as limestone and marble. Learn about its applications. Understand the basic character of calcium carbonate and how this influences its properties. Understand its role in agriculture and construction. Sodium Bicarbonate (NaHCO3): Explore the properties of this versatile salt, used in cooking, as a leavening agent, as an antacid, in cleaning and many other uses. Analyze sodium bicarbonate in relation to pH, highlighting its alkaline character. Lime: Discover the uses of lime, whether as calcium oxide or calcium hydroxide, from the production of quicklime to its use in water treatment, construction, liming... This video is not just a review, but an opportunity to deepen your understanding of carbonates. We will cover not only concepts, but also practical applications and connections between these compounds, preparing you to face any challenge that chemistry may present in the ENEM.
