What type of chemical reaction is represented by the following equation?
\[\ce{A + BC -> AC + B}\]
When a black metal compound XO is heated with a colourless gas Y2, then metal X and another compound Y2O are formed. Metal X is red-brown in colour which does not react with dilute acids at all. Gas Y2 can be prepared by the action of a dilute acid on any active metal. The compound Y2O is a liquid at room temperature which can turn anhydrous copper sulphate blue.
- What do you think is metal X?
- What could be gas Y2?
- What is compound XO?
- What is compound Y2O?
- Write the chemical equation of the reaction which takes place on heating XO with Y2.
