The announcement is part of the agency’s efforts to address pollution caused by the chemicals known as PFAS—per- and polyfluoroalkyl substances—a class of nearly ubiquitous chemical compounds known to endanger human health. EPA proposed designating the two most studied and common types of PFAS...
Food dyes are chemical compounds developed to enhance the appearance of food by giving it a vibrant, yet artificial color. The food dyes Red 40, Yellow 5, and Yellow 6 are the most common and make up roughly 90% of all the food dyes used in the US. The use of artificial dyes in fo...
Based on numerous rainwater tests over long periods of time, it has become obvious that aluminum is the most common and abundant chemtrail toxin, therefore it should not surprise us that this chemtrail type is the single most commonly sprayed type.This chemtrail type is usually sprayed 12 to ...
Identify the IUPAC name and the common name for each of the following compounds. What is the name of the covalent compound Cl2O? Name the following ionic compound Zn(ClO_2) using the IUPAC chemical nomenclature. Provide two details about t...
We will conclude by seeing how these trends can be used to predict chemical properties of the elements. WEEK 3 Now that we know the structure of an atom, we can explore how atoms combine to form either molecular or ionic compounds. Then we will learn the rules of nomenclature that ensure...
