Question

What happens when the following metals react with oxygen ( write chemical equation
(a) sodium
(b) zinc (c) magnesium

​

Answer 1

Answer:

a)Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2)

b)Under normal conditions, zinc does not react with water. However, hot zinc(Zn) reacts readily with steam to produce zinc oxide and hydrogen gas

hope this is helpful..

Answer 2

Answer:

i=Magnesium reacts with oxygen found in the air to form magnesium oxide

ii= Sodium react with oxygen producing a lot of heat and light after the reaction , sodium will left

iii= Zinc react to produce zinc hydroxides
