When a zinc plate is placed in an aqueous solution of copper sulfate, elemental copper forms, as represented by the equation above. Which of the following represents the reduction half-reaction of the

What happens when a piece of(a) zinc metal is added to copper sulphate solution?(b) aluminium metal is added to dilute hydrochloric acid?(c) silver metal is added to copper sulphate solution?Also, write the balanced chemical equation if the reactionoccurs

Zinc is more reactive than copper and hence it displaces copper from copper sulphate solution. As a result a number of holes were observed on the zinc plate.

A displacement reaction is one method for obtaining copper metal from aqueouscopper(II) sulfate.Identify another method for obtaining copper metal from aqueous copper(II) sulfate....................................................................................................................................... [1][Total: 11]It takes place because iron is hghe than copper in the reactivity seres so it is able to displace copperfrom the reactionfe2+CUSO4=Feso4+cu

Which of the following is a displacement reaction?Sodium + chlorine → sodium chlorideLithium + lead nitrate → Lithium nitrate + leadMagnesium + oxygen → magnesium oxideCalcium carbonate → calcium oxide + carbon dioxide2What would you expect to see when zinc is added to copper sulfate solution?The solution turns from colourless to blue and a brown solid is formedNo reactionThe solution turns from blue to colourless and bubbles/fizzing occursThe solution turns from blue to colourless and a brown solid is formed3The order of decreasing reactivity for four metals is potassium, calcium, zinc and copper. Which of the following pairs of metals and solutions will result in a displacement reaction?Calcium plus potassium sulfateCopper plus potassium sulfateZinc plus calcium chloridePotassium plus copper nitrate4What are the products of the reaction of silver oxide with hydrogen?No reaction takes placeSilver plus oxygenSilver plus waterSilver hydroxide
