QUÍMICA ENEM PPL 2020! "Quando as pilhas, que contêm metais pesados, são descartadas no lixo..."

Hey everyone! In this video, we'll be solving question 101 of the chemistry section (blue booklet) of the 2020 ENEM PPL exam (2nd application)! When batteries containing heavy metals are discarded in regular trash, their casing can rupture, releasing their contents into the environment. Upon reaching the soil, a heavy metal can become trapped in the upper layers through three processes: reaction with organic molecules containing oxygen or nitrogen in their structure, adsorption onto clays and minerals, and reaction with hydroxyl, sulfide, or methyl groups, forming an insoluble precipitate. Based on the information presented, the following compounds are likely to form in the soil: Alternatives The Chemistry Classroom channel has content aimed at students who struggle with this subject! Simple, clear, and easy-to-understand explanations! If CHEMISTRY is the terror of your studies, it's time to change that perception!!! Hey everyone, don't forget to subscribe to the channel, leave a comment and like the videos, and share with your friends who are complete zeros in chemistry! My goal is to bring free, quality basic content to students in Brazil! We're in this together!!!! Instagram: professordiegofares #enemppl #enemppl2020 #resolucaoenemppl
