Useful substances from crude oil
The formula for ethanol is:
What is formed when ethene reacts with steam?
Ethanol and propene
Ethanol and phosphoric acid
What is one of the advantages of making ethanol by fermentation?
The raw material is a renewable resource.
The ethanol formed is impure.
It is a continuous process.
In the reaction, ethene ==> poly(ethene) ...
... Propene is the monomer.
... ethene is the monomer.
... poly(ethene) is the monomer.
Why can polymers be difficult to dispose of?
They are difficult to burn.
They are very reactive.
They do not break down easily.
