Chemistry homework help pls :^)

C10h12-->3c2h6+c2h4

GCSE Chemistry AQA Higher Organic Chemistry:

Hello, I've got a question on my chemistry homework which has really stumped me, any help would be greatly appreciated 🙂

'When hot vapours of decane are passed over a heated catalyst a reaction can occur. Write an equation to show ethene and one other product being formed in the ratio 3:1' (2 marks)

I'm sorry, but the member who answered your question has made a mistake in their equation, and I believe it's better you understand how to approach the question rather than just copy the equation.

The process is known as catalytic cracking - the breakdown of large alkanes into smaller alkanes and alkenes by using a catalyst (usually Zeolite).

Decane is C10H22 and 3 ethene (C2H4) molecules need to be formed. There are 10 C atoms in decane, and 6 of them are needed for the formation of ethene. The remaining C and H atoms form the other product.

Hope you understood the method you need to use for these type of questions!

youre complete right i double checked and i have made a mistake its C10h12-->3c2h6+c4h4.

Weren't ethENE molecules supposed to be formed? Furthermore, the molecular formula of decane is C₁₀H₂₂, so if you typed out the question right, you should end up with C₁₀H₂₂ --> 3C₂H₄ + C₄H₁₀

Thank you, organic chemistry definitely isn't my strong point lol
