"Displacement reactions also play a key role in extracting metals in the middle of the reactivity series." Justify this statement with two examples.
Why can metals high up in the reactivity series not be obtained by reduction of their oxides by carbon ?
Name the type of chemical reaction in which calcium oxide reacts with water. Justify your answer by giving balanced chemical equation for the chemical reaction.
Which of the following is a redox reaction, but not a combination reaction ?
Study the experimental set-up shown in the diagram and write chemical equation for the chemical reaction involved. Name and define the type of reaction. List two other metals which can be used in place of iron to show the same type of reaction with copper sulphate solution.
Zn + 2CH₃COOH → (CH₃COO)₂Zn + H₂ The above reaction is a :
