Complete these word equations for displacement reactions: 1) Magnesium + silver nitrate → ____ + sil

What you are looking for in these equations

Each one is a displacement reaction: a more reactive metal pushes a less reactive metal out of its salt solution. The new salt is made from the reactive metal plus the nitrate or sulphate ion.

Equation 1: Magnesium with silver nitrate

Magnesium is more reactive than silver, so it displaces silver from silver nitrate.

• Product salt: magnesium nitrate
• Displaced metal: silver

So: Magnesium + silver nitrate $\rightarrow$ magnesium nitrate + silver

Equation 2: Making aluminium sulphate and copper

If the products include aluminium sulphate + copper, the starting salt must be copper sulphate (aluminium displaces copper).

So: Aluminium + copper sulphate $\rightarrow$ aluminium sulphate + copper

Equation 3: Producing zinc sulphate and copper

If the products include zinc sulphate + copper, the metal reacting must be zinc, and the salt must be copper sulphate.

So: Zinc + copper sulphate $\rightarrow$ zinc sulphate + copper

Equation 4: Iron with lead nitrate

Iron is more reactive than lead, so it displaces lead from lead nitrate.

• Product salt: iron nitrate
• Displaced metal: lead

So: Iron + lead nitrate $\rightarrow$ iron nitrate + lead
