Neco Model Questions Vol1 2019 Chemistry Question 14
Practice objective / multiple choice question 14 from the 2019 Neco Model Questions Vol1 Chemistry examination.
A 10.0 g mixture of cyclohexane (\(C_6H_{12}\)) and hexane (\(C_6H_{14}\)) is subjected to catalytic cracking. The only products obtained are ethene (\(C_2H_4\)) and butane (\(C_4H_{10}\)). The mass of ethene collected is 4.20 g.\n\nAssuming the cracking reactions are:\n\[C_6H_{12} \rightarrow 3\,C_2H_4\]\n\[C_6H_{14} \rightarrow C_2H_4 + C_4H_{10}\]\n\ncalculate the mass of cyclohexane present in the original mixture.
