Listing 10 of 24 questions
The transition elements occupy the central block of the Periodic Table. Iron and copper are typical transition elements. The compounds of transition elements are often coloured. What is the colour of iron(hydroxide? A redox reaction happens when iron filings are added to aqueous copper(sulfate. Fe+ Cu2+Cu+ Fe2+Describe what is observed during this reaction. Use the equation to explain that oxidation takes place in this reaction. Use the equation to explain that reduction takes place in this reaction. Compounds containing ions of transition elements are often used as catalysts. Name a catalyst that is the compound of a transition element and state the reaction it catalyses. name reaction Catalysts increase the rate of reaction by providing an alternative reaction pathway with a lower activation energy. Explain why catalysts are used in industry.
