reaction of sodium, magnestum &
aluminium metal with water t arrange
them in incre
asing reactivity.
Answers
Answer:
1) Reaction with oxygen- Sodium catches fire when kept open in the air , so sodium reacts very vigorously with oxygen.
Magnesium reacts with oxygen only on whereas copper reacts with oxygen on very strong heating.This reaction shows that here sodium is the most reactive metal and copper is the least reactive metal show the decreasing order of reactivity is Sodium, magnesium and then copper.
2)Reaction with water- Sodium reacts very vigorously even with cold water.
Magnesium reacts slowly with cold water but rapidly with hot, boiling water, whereas copper does not react even with steam. This activity shows that your sodium is the most reactive metal and copper is the least reactive metal. Show the order of their decreasing reactivity is Sodium, magnesium and then copper.
