ANSWER

How much potassium chlorate should be heated to produce 2.24L of oxygen at NTP?

Preeti Dabral 1 year, 8 months ago

When potassium chlorate is heated, then following reaction takes place:

2KClO₃ {tex}\rightarrow{/tex} 2KCl + 3O₂

Molecular mass of 1mol KClO₃ = 39 + 35.5 + 3 {tex}\times{/tex}16= 122.5 g

Molecular mass of 2 mols of KClO₃ = 2{tex}\times{/tex}122.5 g =245 g

Volume occupied by 3 mol of oxygen = 3{tex}\times{/tex}22.4L = 67.5 L

Therefore, 67.2L of oxygen is produced from 245g of KClO₃

2.24L of oxygen is produced from = {tex}\frac { 245 } { 67.2 } \times 2.24{/tex}= 8.17g of KClO₃

Account Deleted 1 year, 8 months ago

If it is fe2(so4)3 , then the oxidation state of fe is +3 Derivation :- suppose oxidation number of fe is x , but We know that oxidation number of (so4)3 is -6 so calculating :- 2×x + (-6) = 0 x = 3

Ethene is a molecule with a lone pair of electrons. It is a strong electron donor, meaning it can donate electrons to other molecules. This is why it is often used in organic chemistry to create molecules with a high degree of flexibility. Ethene can also form a bridge between molecules, which is why it is often used in organic synthesis.
