It was on the verge of extinction but thanks to its protection today its population is very stabilized. Like the tig

My favorite subject in this semester

 In this semester, I enjoyed many subjects, organic chemistry and general farmacology for example, but analytic chemistry is the subject I more enojoyed. In this subject, we learned about how has a complete cualitative and cuantitave analysis about a  solid sample, for know everyone components of we sample, both cations and anions, where should we be attentive a change color in the sample, or if was formed a precipitate, should we be attentive because any minimum change can we deliver importan information of the composition of we sample . Also in this subject we learned how the pH and the  complexings concentration, (amoniac for example) can chamge the chemistry reactions, and we learned too how use this in our favour,because in occasions we has need selective precipitations in to a laboratory, and other example is when we has need perform selective reduction, where the protons and complexings concentrations are very important.   I like a lot of this asignature in large part by the tea
