HELPFrom the information presented in the activity series of metals below (4 metals included), answer the following question. In a single replacement reaction, would aluminum replace magnesium to form a new compound or would there be no reaction?



magnesium (most reactive)

aluminum

zinc

iron (least)

a)there would be no reaction

b) aluminum would replace magnesium to form a new compound

a)there would be no reaction

Explanation:

The activity series of metals has many functions. The one applicable to this problem is that it can be used to determine whether a reaction will occur or not. Also, based on the positions of metals in the series, we can know how reactive a metal is compared to another.

In a single displacement reaction, a metal replaces another metal based on their position on the activity series. Metals that are higher in the series are generally more reactive than others below them and so will displace them.

Would aluminum replace magnesium to form a new compound or would there be no reaction?

Magnesium is higher than aluminum in the activity series. Therefore it is more reactive than aluminum. No reaction will occur.
