• ବିସ୍ଥାପନ ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା • ଦୈତ ବିସ୍ଥାପନ ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା • ଜାରଣ ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା • ବିଜାରଣ ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା • ସଢ଼ା ଅବସ୍ଥା • କ୍ରମକ୍ଷୟ balance Equations ​Displacement and Double Displacement Reactions: ​The video explains displacement reactions using examples like Iron (Fe) reacting with Copper Sulfate (CuSO_4) to form Iron Sulfate and Copper [01:42]. ​It introduces the reactivity series (Potassium, Sodium, Calcium, Magnesium, etc.) to explain why certain elements displace others [02:56]. ​Double displacement is illustrated with the reaction between Sodium Sulfate (Na_2SO_4) and Barium Chloride (BaCl_2) [06:04]. ​Oxidation and Reduction (Redox): ​Oxidation: Defined as the addition of Oxygen or the removal of Hydrogen [12:52]. An example provided is Copper reacting with Oxygen to form Copper Oxide (CuO) [08:01]. ​Reduction: Defined as the removal of Oxygen or the addition of Hydrogen [13:08]. ​The video discusses simultaneous oxidation and reduction (Redox reactions) using the reaction of Manganese Dioxide (MnO_2) with Hydrochloric Acid (HCl) [11:35]. ​Corrosion and Rancidity: ​The instructor briefly touches upon the concept of corrosion, specifically mentioning the tarnishing of silver [15:26]. ​Rancidity: The video explains why food items like chips are packed with Nitrogen gas to prevent oxidation and keep them fresh [17:53]. ​Balancing Chemical Equations: ​A significant portion of the video is dedicated to teaching how to balance equations using the LHS (Left Hand Side) and RHS (Right Hand Side) table method [18:24]. ​Examples balanced include: ​Aluminum + Oxygen \rightarrow Aluminum Oxide (Al_2O_3) [18:38]. ​Sodium + Oxygen \rightarrow Sodium Oxide (Na_2O) [23:19]. ​Iron Oxide + Aluminum \rightarrow Aluminum Oxide + Iron [25:30].
