What is the reaction of Copper Oxide with Magnesium?
Mg + CuO 🡪 MgO + Cu
What happens in the reaction of Copper Oxide with Magnesium?
Magnesium displaces copper from copper oxide and combines with oxygen to form magnesium oxide.
What type of reaction is the reaction of Copper Oxide with Magnesium?
It is an example of a REDOX reaction.
What is oxidised in the reaction of Copper Oxide with Magnesium?
The magnesium (Mg) is OXIDISED.
What is reduced in the reaction of Copper Oxide with Magnesium?
The copper oxide (CuO) is REDUCED.
What is the reducing agent in the reaction of Copper Oxide with Magnesium?
The magnesium (Mg) is the REDUCING AGENT.
What is the oxidising agent in the reaction of Copper Oxide with Magnesium?
The copper oxide (CuO) is the OXIDISING AGENT.
How can metals below carbon in the reactivity series be reduced?
By heating with carbon.
What is an example of reducing metal oxides using carbon?
2Fe2O3 + 3C 🡪 4Fe + 3CO
What happens when a higher metal displaces a lower metal from a solution of metal salts?
A higher metal will displace one lower down the reactivity series.
What is an example of displacing metals from solutions of metal salts?
2AgNO3 + Cu 🡪 Cu(NO3)2 + 2 Ag
What do metals above copper in the reactivity series produce when reacting with acid?
They produce a SALT and HYDROGEN.
How can hydrogen be collected during the reaction of metals with acid?
By upward delivery or over water.
What is an example of a reaction of a metal with acid to produce hydrogen?
Mg + 2HCl 🡪 MgCl2 + H2 Magnesium Chloride
