Properties of Oxygen and Hydrogen
This lesson covers the properties, preparation, and tests of oxygen and hydrogen gases. It explains the role of these gases in the environment and their reactions with other elements. The lesson also includes information on the physical states of oxygen.
- 08:52 “You can prepare oxygen by decomposing of hydrogen peroxide. When you have hydrogen peroxide, if you want to decompose it, breaking it into two is a chemical process, but decomposing it will give you water and oxygen. Fro...”
- 08:05 “The gas produced is collected in an upside-down gas jar filled with water. In our next slide, you will see a picture of this. Our oxygen is being collected. As the oxygen collects in the top of the gas jar, it pushes the...”
- 18:02 “In that way, gases can be produced in the school laboratory. The fourth way to produce gas in the school laboratory is when it softens on the ghost combustion in air. Take for instance, you use a paper, you light it up w...”
Oxides of Carbon
This lesson covers the two types of carbon oxides: carbon monoxide and carbon dioxide. It explains their formation, characteristics, and methods of preparation in the laboratory. The lesson also defines the term allotrope and discusses the economic importance of these oxides.
- 33:48 “so for example this is actually used by a manufacturer of glass, so you know, add detergents, okay, so then for this one is deployed in baking powder, or to discharge our carbon-folks, right, so as that helps to reduce t...”
- 07:02 “to take is carburetor oxide. But alongside, carburetor oxide is also formed. Like you can see in this equation here, this equation is showing us how that happens. So, then this one is a ethythic dioxide. So, that is actu...”
- 29:44 “salt, don't forget that, all right? So, the reacts are insoluble, so the common methods for preparing them are very few, though, we need to understand this, because if you don't understand how these are, because we use t...”
