Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Students learn to classify matter as elements, compounds, and mixtures. Matter: Classification of Matter: Students learn to classify matter as elements, compounds, and mixtures and to distinguish ...

The conceptual and technical approaches that led to the explosive growth of combinatorial chemistry began approximately 20 years ago. In the past decade, combinatorial chemistry has continued to ...

When hearing someone describe the typical preparation of organosulfur compounds, it’s clear the approach is not a very sustainable one. Mixtures of sulfur compounds naturally in crude oil are first ...

The film explains the fundamental concepts of matter, focusing on atoms and molecules. It highlights that everything in the world is made up of atoms, which combine to form molecules. There are over ...

In this episode Dr Sunayana Bhargava and Tulela Pea talk about the building blocks of all matter: atoms. They also discuss how they combine in different ways to make molecules, compounds and mixtures.

Physicists have developed a novel technique that can detect molecular variants in chemical mixtures -- greatly simplifying a process that is one of the most important, though time-consuming, processes ...

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

In quality control and chemistry, analytical samples are usually mixtures. Understanding the main compound’s assay and the number of impurities or other unwanted substances in the sample is essential ...
