A student wants to compare the reactivity of an unknown metal, Q, with that of zinc.
Both metals are more reactive than silver.
The student is provided with:
• silver nitrate solution
• metal Q powder
• zinc powder
• a thermometer
• normal laboratory equipment.
No other chemicals are available.
Describe a method the student could use to compare the reactivity of metal Q with
that of zinc.
Your method should give valid results

Since both metals are more reactive than silver carry out a metal displacement reaction(https://science-revision.co.uk/metal...reactions.html) using each of the metals.

Use 2 insulated polystrene cups with lid.
put 25 ml of O.05 M silver nitrate in each cup, measure the temperature every minute for 5 minutes to get mean temp of the silver nitrate.
Put 1g of Zn and metal Q into each flask and stir. Record the temp every 30 seconds.
The more reactive the metal the larger should be the temp rise.
