Why Does Metal Rust? – Reactions Q&A

Well folks, you asked and we’re answering. That’s right we heard you. Peter Sterckx wants to know why do metal things grow. Well, here’s Sophia with an explanation. Corrosion is caused by a redox reaction, which is actually two simultaneous reactions in one: Reduction and Oxidation. (Oncscreen: 1) Reduction) A reduction reaction occurs when some […]

Metal Meltdown | Brainiac75

Welcome! In this video I will show you some low-melting metals and alloys. Usually we think of metals being very sturdy, solid and difficult to melt without excessive heat. That is true for many metals like this stick of molybdenum that will first melt at over 4,700°F. But my butane blowtorch maxes out at around […]

Alkali metals in water – Chemical elements: properties and reactions (1/8)

There are six alkali metals: Lithium, sodium, potassium, rubidium, cesium and francium. They are all soft metals which can be cut with a knife. In air the elements quickly become coated with compounds that form on the metal’s surface. Here, for example, is lithium. When we slice it, you can see the metallic lustre but […]

Magic metal – fusible alloys

This piece of metal behaves in a very unexpected way when we place it into hot water. So what’s going on here? This is Field’s metal. It’s a fusible eutectic alloy of indium, bismuth and tin which means that it melts at a lower temperature than that which we might expect and it also melts […]

Metal vs. Bacteria

Medicine has changed a lot in the last hundred years. We have better technology to look for problems, and if we find one, we’re much more likely to be able to fix it. And one of the most important fixes is that these days, we have antibiotics, which are really good at killing off harmful […]
