Question

Write metal reactivity series and its application in the form of four equations.

Answer 1

Answer:

Explanation:

This article is on reactivity series of metals. Metals are usually inclined to form cations through electron loss, reacting with oxygen in the air to form oxides over various timescales (iron rusts over years, while potassium burns in seconds). ... 4 Na + O2 → 2 Na2O (sodium oxide) 2 Ca + O2 → 2 CaO (calcium oxide)
