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.
- 16:16 “as it's consumed by plants. You know, plants consume them in. It's just like we breathe in oxygen, and breathe out the carbon dioxide. Then, the carbon dioxide would breathe out is what plant consumes also, all right? Ju...”
- 23:14 “But, in this case, why you continuously bump lead that? This kind of force into the solution becomes so clear, all right? Because of the formation of calcium, hydrogen, trans-carbonate, all right? So, basically, this equ...”
- 06:15 “the carburetor oxide is passed through the delivery tube into this water, this is a water on pneumatic trough. So, pneumatic trough has a gas jar standing on it. So, that is the gas jar that has been evacuated, okay? So,...”
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.
- 02:21 “in many minerals, such as cell hydrocabons, in natural gas, petroleum, et cetera. In air, carbon dioxide is present in small quantity, which is 0.03 percent. Of course, we know that part of the constituents of air, so ou...”
- 18:41 “So how do we carry this carbonization process? Now basically, you find out that, like we mentioned before, for carbonization, it's a complex mixture, what's it called? Compounds composed of a million of carbon, all right...”
- 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...”
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
- 18:43 “with the Ozzides. Ozzides ion to release the electrons necessary for reduction of the matter. What am I talking about? So carbon of the A, carbon that reacts with the oxygen gives us CO which is carbon two or that plus t...”
- 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...”
- 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,...”
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.
- 01:36 “As long as you are living, you need oxygen to breathe. This oxygen is being taken up by animals which then converts it to carbon dioxide. Since animals will breathe in oxygen and will breathe out carbon dioxide. The carb...”
- 16:16 “This mix together, you get the salt and hydrogen gas, which becomes zinc chloride and hydrogen. When this is decomposed, you get zinc chloride and you also get hydrogen. And as a result, hydrogen is being stored in this...”
- 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...”
Definition and Classification of Chemicals
This lesson defines chemicals and explains their various forms, including solids, liquids, and gases. It also classifies chemicals their hazardous nature and discusses safety measures when using them.
- 12:11 “ion is one to one. That's why I have NACL. Then we have methane, which is CH4. It's an organic compound. So, you have an atom of carbon and four atoms of hydrogen. So, the ratio of hydrogen to the carbon is four ratio on...”
- 10:28 “or topic is the covalent and the ionic bond. If you look at this particular diagram, this is a diagram of water. So, you see an atom of oxygen. You see two atoms of hydrogen on this side, which is H2O. Now, what is coval...”
- 06:30 “Now, for one carbon present in any particular compound of carbon, you have to use it to determine what's referred to as alotrupy. Alotrups of carbon talks about the shapes in which carbon can exist. Now, we have diamond,...”
Chemical Symbols and Formulae
The lesson covers the symbols of the first 20 elements and how to write chemical formulae and equations. It explains the differences between elements, compounds, and mixtures, as well as the concept of radicals and valency. The laws of conservation of mass and constant composition are also discussed
- 01:34 “the symbols of the different elements that combine chemical to form the compound, E, G, calcium carbonate, or calcium triadal carbonate for. Whereby, it contains carbon and it contains calcium, one atom of calcium carbon...”
- 17:18 “ion 3 chloride. The next KOH plus CO2 to give us K2 CO3 plus H2O. And then the next is C6 H2FO6 plus O2 to give us CO2 plus H2O. And the last is KCLO3 to give us KCL plus O2. All the equations are no balance. You need to...”
- 16:27 “And on the product side, I actually have 4. I have 6 times 2, 6 times 2, hydrogen. And that's what we give me 12. You can see it's balanced. The last but not the least, which is oxygen 502. 5O2 means 5 times 2. 5 times 2...”
