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...”
- 20:20 “is used for the manufacture of pharmaceutical products and also as a solvent, okay? So for co-ta, co-ta is a mixture of more than 200 different substances, which can be separated by a fraction of distillation, so of cour...”
- 22:46 “will have a polyethnose acid or wood gas, actually, so then for the polyethnose acid, which is a liquid fraction of co-tax million etanote acids, all right? Which contain propanone, which contain metanone, and also some...”
Sources of Energy
The lesson covers different sources of energy, including renewable and non-renewable types. It explains how energy is used in society and discusses the environmental impacts of various energy sources. Specific examples include petroleum, natural gas, solar energy, and wind energy.
- 19:33 “It causes global warming. We have oil spillage. This is the release of liquid petroleum hydrocarbon into the environment. Now, this is due to human activities. Now, due to this, human activities can cause pollution. That...”
- 15:38 “We have what the acid drain, we have the global warming. We have the greenhouse effects. We also have the global warming, like I said. We have the oil spillage. Now, we're taking them one after the other. Let's first tak...”
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
- 00:00 “Hello everyone. I'm Mrs. Olabimpe Ayoko. I'm here to teach SS 3 chemistry and the topic is Metals and its compounds. So at the end of this lesson, everybody is expected to be able to define Metals with examples. The frie...”
- 09:56 “with carbon falls out of the atmosphere. So for this one, which is also carbonic acid, a weak acid. Why this one also reacts with water? So give you H2 SO3. So still we have SO3 also, which is an hydride, can still react...”
- 11:30 “After you earlier, the reaction of hydrogen with metas or nonmetas is known as hydrace. So when hydrace with nonmeta, they form covalent compounds. Examples are ammonia. We have methane stage 4. We have hydrogen chloride...”
