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.
- 11:41 “So, carbon monosa actually combines with hemoglobin, which is a HB here, so, in the red blood cells to form a carbon dioxide hemoglobin. So, it forms carbon dioxide hemoglobin, as you can see, this equation here. So, bas...”
- 10:52 “So, now, the air containing even less than 1% of carbon monosa, okay, can be fatal. Very, in fact, just 1% of it can be very dangerous of it, okay? When you breathe in, for about 10 to 15 minutes, the person can eventual...”
- 00:48 “Our carbon can be prepared in laboratory. That's carbon two oxides, I mean, all sides of carbon can be prepared in the laboratory. So, the carbon two oxides and carbon four oxides. So, now, basically, we wanna talk about...”
Carbon and its Allotropes
The lesson covers the characteristics of carbon as an element and its various forms, known as allotropes. It explains the presence of carbon in nature, its compounds, and the two types of carbon oxides. The importance of carbon in living systems and its economic significance is also discussed.

- 00:48 “of wood and coal, then transoccarbonate and hydrogen transoccarbonate as the last one. All right, now introduction. Basically, this is one of the very vital topics we have in chemistry. So I believe that the classes is r...”
- 01:36 “So now, carbon occurs in the free native states as well as in the combined states. So carbon and its compounds are widely distributed in nature. So of course, as we go on, we'll see it in the lesson. Then now, in each el...”
Metals and their compounds
This lesson covers the characteristics of metals, including their ability to lose electrons and form positive ions. It discusses the classification of metals, their physical properties, and examples of common metals such as sodium, magnesium, and aluminum. The lesson also includes information on the

- 17:11 “very expensive. So this one is preferred, preferred to that one, except that the very reactive methods, you can't both carry out electrolysis on them. So reduction of others. The less electro-positive methods like zinc,...”
- 17:57 “four or that. This is a reduction process. Carbon two or that is a reducing agent. It reduces ion three or that to elemental ion and carbon four or that. The reduction of suffice. Remember the oxide can be reduced and no...”
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.
- 17:08 “Now, the test for hydrogen. The pop-up test, when it leads tapah, when using a leads tapah, it will produce an audible pop when placed in hydrogen glass, gas. Gases can be produced in the school laboratory when a compoun...”
- 09:42 “Now we have here lead oxide. When you go through tamarge composition, it breaks into lead and oxygen. Then your oxygen is being taken at this point and for tamarge composition of hydrogen peroxide, because it includes wa...”
- 07:20 “If you have seen the welders, when they begin to weld, the fire that comes out is as a result of this. It is used in the large-scale production of sintences gases. It is also used for artificial respiration in oxpitu. An...”
