Verified Answer
Which one of the following metal reacts vigorously with oxygen and wat...
The correct answer is A) Sodium. Sodium reacts vigorously with both oxygen and water. When exposed to oxygen, sodium rapidly combines with it to form sodium oxide (Na2O) or sodium peroxide (Na2O2), depending on the conditions. This reaction is exothermic and often accompanied by a bright yellow flame.
In the presence of water, sodium reacts vigorously to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction is highly exothermic and can result in the release of heat, formation of hydrogen gas bubbles, and the production of sodium hydroxide solution.
Potassium (option B), calcium (option C), and magnesium (option D) also react with oxygen and water, but sodium is generally more reactive than these metals, exhibiting a more vigorous reaction.
