Step 1
Use this information to put the four metals in order of reactivity from the least reactive to the most reactive.
Answer
To determine the order of reactivity of the metals P, Q, R, and S based on the observations:
- Metal P showed very slow bubbling and some metal remained, indicating it is the least reactive.
- Metal R produced bubbles slowly and also had no metal remaining, suggesting it is more reactive than P but less so than Q and S.
- Metal Q produced bubbles quickly with no metal remaining, indicating it is more reactive than both P and R.
- Metal S produced bubbles very quickly with no metal remaining, marking it as the most reactive.
Thus the order from least reactive to most reactive is: P, R, Q, S.
