Question d
Using their atomic symbols, arrange the metals, copper, calcium, zinc and magnesium in order of decreasing reactivity with dilute hydrochloric acid.
Worked Solution & Example Answer:Using their atomic symbols, arrange the metals, copper, calcium, zinc and magnesium in order of decreasing reactivity with dilute hydrochloric acid. - Junior Cycle Science - Question d - 2008
Step 1
Using their atomic symbols, arrange the metals in order of decreasing reactivity with dilute hydrochloric acid.
Answer
The metals can be arranged in order of decreasing reactivity as follows:
- Calcium (Ca)
- Magnesium (Mg)
- Zinc (Zn)
- Copper (Cu)
This order is based on the position of these metals in the reactivity series, which indicates that calcium is more reactive than magnesium, followed by zinc, with copper being the least reactive.
