What happens to large hydrocarbon molecules during cracking?
Cracking breaks large hydrocarbons into smaller, more useful molecules by heating them.
Cracking changes large hydrocarbons into carbon dioxide and water by burning them.
Cracking joins small hydrocarbons into larger, less useful molecules by cooling them.
Cracking removes carbon atoms from large hydrocarbons by dissolving them in water.
