Precious metals like gold, silver, platinum, and rhodium are expensive because they're rare in Earth's crust. But are they rare in the universe? Why is it so hard to make some of the chemical elements? Where do heavy metals come from,...

Lead is really useful when you add it to things like paint and gasoline. Problem is, it’s also poisonous. Hosted by: Hank Green

The chemical process of catalysis happens in a myriad of places in our modern world - from industry to inside your cells. Our knowledge of catalysis today springs from Elizabeth Fulhame, who over 225 years ago became the first person to...

In USA in the 1970s, 200,000 tonnes of lead was added to petrol every year. Now leaded petrol for cars is banned. Discover the dangers of tetraethyl lead in petrol. Chemistry - Chemical Industries - Learning Points. Midgley Junior added...

In this video, we learn about the metal palladium, which is part of the elite group of metals called the Platinum Group. The video highlights the properties of Palladium, including its usefulness as a catalyst, high resistance to wear...

Automotive data is available from OBD-II codes that are standard for engine monitoring of light duty vehicles (passenger cars) starting in year 1996. Newer vehicles may include additional sensors from other...

The video discusses atmospheric pollution and the effects of burning fossil fuels. It explains the pollutants created through combustion, such as carbon dioxide, particulates, carbon monoxide, sulfur dioxide, and nitrogen oxides. The...

This video provides an explanation of what a catalyst is and how it can increase the rate of chemical reactions. The concept of activation energy is introduced, and it is explained that catalysts lower activation energy, allowing more...

Through animation and video footage students will learn that there are two basic types of catalysts, heterogeneous and homogeneous. Students will come to understand that catalysts have many practical applications and that scientists use...
