Q

Why are carbon and hydrogen in the reactivity series?

A
  • Metals less reactive than carbon can be extracted, more reactive cannot
  • Metals more reactive than hydrogen react with acid, less reactive will not

Q

What is a reduction by carbon?

A
  • Compound reacts with carbon, produces element + CO2
  • Can be done if element is less reactive than carbon
    2Fe2O3 + 3C –> 4Fe + 3CO2
