Basic Binary Decomposition Reactions
We start with the simplest form of decomposition reactions. An example we cover is sodium chloride (NaCl) decomposing into sodium (Na) and chlorine gas (Cl2).
Decomposition of Metal Carbonates
Next, we explore how metal carbonates break down. We'll look at calcium carbonate (CaCO3), which decomposes into calcium oxide (CaO) and carbon dioxide (CO2).
Decomposition of Metal Hydroxides
Following that, our focus shifts to metal hydroxides. For instance, sodium hydroxide (NaOH) decomposes into sodium oxide (NaO) and water (H2O).
Decomposition of Oxides
Lastly, we examine the decomposition of oxides, such as sodium oxide (Na2O) breaking down into sodium (Na) and oxygen gas (O2).
By categorizing these decomposition reactions, we can identify patterns that help in predicting the products of these reactions. This video is designed to simplify these concepts for students at the general chemistry level.

Sir, how to balance the charges or criss-cross the charges of COMPOUNDS in reactant to form a single compound product as like of Combination reaction between two elements to form a compound ? Explain.

Like in combination reaction between elements, a compound product is formed by balancing the charges of elements, Does it also happens in combination reaction between two compounds to form a single compound as a product. And how it is done ? Explain in detail with a simple example.

Sure: Calcium oxide (CaO) + Carbon dioxide (CO2) → Calcium carbonate (CaCO3) Ammonia (NH3) + Hydrochloric acid (HCl) → Ammonium chloride (NH4Cl) Sulfur dioxide (SO2) + Water (H2O) → Sulfurous acid (H2SO3)

I think you made a small mistake at 4:40, the formula of aluminum carbonate should be Al2(CO3)3, not Al2(CO3)2

sir i usually watch your videos, and i just came here to understand a question that is not in this video , is CCl3F polar or non polar i know the electronegativities of Cl and F are different but they seem to have the same amount of lone pairs as Cl in CCl3F, and symmetric distribution of lone pairs result in a non-polar molecule

Sir, I have a doubt that why Combination and Decomposition reaction is difficult to predict as compared to other reactions ? Please explain with example
@wbreslyn 4 ай бұрын
Mainly because decomposition had five major patterns you need to learn. So it's not like double rep where you learn one pattern, here there are multiple. I go over each in the video so that should help! Combo is similar (sort of the reverse of decomp).

Sir, why in decomposition reaction of MCO3 -----> MO + CO2, it forms MO + CO2 and why not M + CO3 ? Please explain in depth

Sir, also in MOH ------> MO + H20, how it forms H20 and MO and why it doesn't form M + OH ?
@madhorai2167 4 ай бұрын
@@Sumit22344actually what you are asserting that why not CO3 can be understood by the fact that CO3 Will involve 6 bonds and maximum covalency of carbon is 4 only because of the absence of d orbital. Hence , this compound CO3 doesn't exist.... Note : CO3²- exist because here it is not exceeding its covalency

Probably not in a way that would result in adequate learning. You could focus on the first type, that is the most common in general chem.

How do you predict the products of chromates? Lets say, (NH4)2Cr2O7. Cr2O3 being one of the products is understandable but I assumed the other one would be NH3 but Its actually N2.
@wbreslyn 4 ай бұрын
That dichromate ion is a strong oxidizer. So that plays a big role in N2 instead of NH3 being formed.
