ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା ଓ ରାସାୟନିକ ସମୀକରଣ Part-1 Class-x

• ମୌଳିକର Valency • ସଂଶ୍ଳେଷଣ ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା • ତାପ ଉତ୍ପାଦି ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା • ବିଘଟନ ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା @ରାସାୟନିକ ପ୍ରତିକ୍ରିୟା ଓ ରାସାୟନିକ ସମୀକରଣ Class-x Valence and Elements [00:00]: The instructor lists elements from Hydrogen to Zinc and explains their valence (combining capacity). For instance, Hydrogen is +1, Oxygen is -2, and Magnesium is +2. ​Forming Compounds [03:10]: A demonstration of how to write chemical formulas by exchanging valences (e.g., how Na and OH form NaOH). ​Common Acids [07:41]: Introduction to symbols and names for essential acids like Nitric Acid (HNO_3), Sulfuric Acid (H_2SO_4), and Hydrochloric Acid (HCl). ​Types of Chemical Reactions: ​Combination Reaction (ସଂଶ୍ଲେଷଣ ପ୍ରତିକ୍ରିୟା) [12:51]: Defined as a reaction where two or more reactants combine to form a single product. Examples include CaO + H_2O \rightarrow Ca(OH)_2. ​Exothermic Reaction (ତାପଉତ୍ପାଦୀ ପ୍ରତିକ୍ରିୟା) [17:34]: Reactions that release heat energy, such as respiration and the burning of natural gas. ​Decomposition Reaction (ବିଘଟନ ପ୍ରତିକ୍ରିୟା) [19:55]: Reactions where a single reactant breaks down into multiple products. This is further divided into: ​Thermal Decomposition [21:02]: Using heat (e.g., breaking down Calcium Carbonate). ​Photolytic Decomposition [26:22]: Using sunlight (e.g., Silver Bromide breaking down). ​Electrolytic Decomposition [28:13]: Using electricity (e.g., the electrolysis of water to produce Hydrogen and Oxygen).
