Question

With which do metals react most easily, water, acid, or oxygen? Give reason to your answer.

Answer 1

Hydrogen bubbles are generated with the reaction with dilute acids and corrosion is observed with the reaction with oxygen. The least reactive metals only react with oxygen

Another answer is


Highly reactive metals react with dilute acid ,water and oxygen .evidence of the reaction with a dilute acid is the formation of hydrogen gas bubble .this reaction involves the transfer of electrons Sharda Motors to hydrogen atoms.the least reactive metal only reacts with oxygen

Answer 2

QUESTION:-

With which do metals react most easily, water, acid, or oxygen? Give a reason to your answer.

ANSWER:-

• Oxygen can react most easily with metals.

EXPLANATION:-

Oxygen can react most easily with metals compared to water and acid because:-

• Metals can react with oxygen to form metal oxides. Oxygen can react with all metals except for gold like Potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, tin, lead, copper, mercury and silver. The less reactive metals like copper, mercury and silver can only be reacted with oxygen and not by acid or water.
• Zinc + Oxygen ----> zinc (||) oxide

• Metals can react with acid to form a salt of metal and hydrogen gas. Acid can react with metals like Potassium, sodium, lithium, calcium, magnesium, aluminium, zinc, iron, tin, and lead. It cannot react with less reactive metals like copper, mercury and silver.
• Sodium + Hydrochloric Acid -----> Sodium Chloride + Hydrogen gas

• Metals can react with water to form metal hydroxides and hydrogen gas. Water can only react with highly reactive metals like Potassium, sodium, lithium, and calcium.
• Calcium + water ----> Calcium hydroxide
