Question

Answer this.. Chemistry class 10 *Chemical Reactions and Equations*

Answer 1

Matal A is Aluminium and Metal B is iron and Blue - coloured solution is copper sulphate solution...

Reaction of metal A with solution C

=============================

Reaction of metal A with C is a type of displacement reaction , Aluminium being highly reactive metal displaces the least reactive metal copper from its salt solution ( Copper sulphate solution )

Aluminium + Copper Sulphate => Aluminium Sulphate + Copper

Al ( s ) + CuSO4 ( aq ) => Al2 (SO4)3 ( aq ) + Cu ( s )

Above equation is unbalanced as Number of Aluminium atoms and sulphate ions are different on both the sides..

2Al ( s ) + 3CuSO4 ( aq ) => Al2 (SO4)3 ( aq ) +3 Cu ( s ) ( Balanced equation )

Reaction of metal B with solution C

=============================

Reaction of metal A with C again is a type of displacement reaction , Iron being highly reactive metal displaces the least reactive metal copper from its salt solution ( Copper sulphate solution ) .

Iron + Copper Sulphate => Iron Sulphate + Copper

Fe ( s ) + CuSO4 ( aq ) => FeSO4 ( aq ) + Cu ( s ) .

The above chemical is equation is already balanced...

The other name for the above reaction is known as single displacement reaction...
