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

- 20:28 “should be able to answer these questions. Number one, explain the term matters with two examples. All right, so an equation to show how a matter can lose electron or electrons to become positively charged. Then question...”
- 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...”
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.
- 10:51 “Bolly point, very high melting point, as I said that. Okay, now look at uses of damod. Now, the unusual brilliant shine, all right? Of damod makes it an invaluable precious of stone. In jewelry, making jewelry, all the j...”

- 15:32 “electroplating can be done easily. So for manufacturing, light pencils and stove paints, as you can see, there is just a picture showing, you know, an example of that, okay? In particular graphite type, you can use for m...”
Solid Minerals in Nigeria
This lesson covers the types of solid minerals found in Nigeria and their locations. It also discusses the importance and uses of these minerals, along with how to draw a map showing their distribution across the country.
- 05:00 “The importance is that it has a great importance to man and the economy of that nation. The uses of goat. Number one, it is used as a basis of international monitris and transaction. So you can use to transact from one c...”
- 04:13 “Number three, it is used in the manufacture of sodium chiosocarbonytes for and the formula is written as e2 cu. So this is very important in the manufacturing of soup. So sodium chiosocarbonytes for is important in manuf...”
- 05:52 “when mixed with bronze, it can be used to make coins. Number three, it is used in making ornaments, pots. Number four, it is used in making electrical wires and cables. And lastly, for making water pipes and cylinders. A...”
Solution and Solubility
This lesson covers the concepts of solution, solute, and solvent. It defines solubility and explains different types of solutions, including saturated, unsaturated, and super saturated solutions. Factors affecting solubility and calculations related to solubility are also discussed.
- 06:15 “Now, let's not know the difference between a true solution and a colleta solution, all right? A true solution is for when solute particles dissolve in such that they are able to get in between the solid particles, take n...”
- 03:54 “all right, type of solution. Now, a solid liquid solution, an example of that is a sugar in water, all right? Now, later, we're going to find out that, you see, the more increase in temperature you have in a particular,...”
- 35:57 “the difference between these 2800 and 1700, at the end of the day, you have 1100, now from where, from 83 degrees Celsius to 40 degrees Celsius, so now 2800 or saturated solution deposited this, don't forget, this is und...”
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.
- 35:26 “so you'll find out that for me, they then also measure three metals, basically that are very soluble in water, in the form of the hydro-t transocarbonyl. Thanks for watching, my name is Charles Christopher, till next tim...”
- 17:03 “So, basically, like here, the metallic carbonate, we use here is calcium carbonate. So, it's calcium carbonate here is actually be heated with XCl, that they use here. You can also use H2SO4. Okay, the same result would...”
- 21:43 “So, now, here we have this. You see, this is a metal here, magnesium metal. They react with this to give us this one, and also this. So, we actually reduce this carbon to this. That's what you are seeing here, okay? So,...”
