Strontium Nitrate - part of our "Berzelius Day" uploading 24 videos in 24 hours. Full video containing this reaction at href='http://www.youtube.com/watch?v=d5ztPGrsgNQ' target='_blank' rel='nofollow'>at NOTE FROM THE PROFESSOR: This...

How do we grow crops quickly enough to feed the Earth's billions? It's called the Haber process, which turns the nitrogen in the air into ammonia, easily converted in soil to the nitrate plants need to survive. Though it has increased...

Preserving the environment and developing agricultural products that do not harm unintended targets are top priorities for many scientists and farmers, as well as environmentalists. It's a new era of crop management known as precision...

Pupil outcome: I can name compounds from their chemical formulae. Key learning points: - The name of a simple metal–non-metal compound ends '-ide' to indicate bonding has occurred. - Some common groups of compounds are metal carbonates,...

This video covers:

- How to test for carbonates by reacting with an acid and then bubbling the gas through lime
water
- How to test for sulfate ion with dilute hydrochloric acid and bariu
m chloride
- How to test for...

We demonstrate a displacement reaction using silver nitrate and copper. A tree-shaped piece of copper is submerged in silver nitrate solution. The silver ions displace the copper and the tree slowly becomes coated with silver metal. At...

The video provides a detailed explanation of how to prepare a pure dry sample of an insoluble salt, specifically lead sulfate. The speaker first explains the solubility rules that determine whether a salt is soluble or not. Then, he goes...

In this lecture video, the speaker discusses the detection and identification of plant diseases. They explain how to detect signs of diseases in plants, such as stunted growth, spots on leaves, and discoloration, and how to identify...

We add potassium iodide and lead(II) nitrate to the opposite sides of a Petri dish filled with water to see how quickly they diffuse. When added to the water, the chemicals spread through the dish and when they meet they react to form...

Ammonium nitrate stored in a warehouse is seen by the Lebanese government as the most likely source of the explosion that ripped through Beirut on August 4.

Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is...
