Question

3. Out of these, which one is more reactive with water?
(a) Copper
(b) Sodium
(C)Iron
(d)Magnesium

Answer 1

Answer:

sodium is more reactive with water.so option (b) is right.

Answer 2

Sodium is more reactive with water:

Explanation:

• Option B) Sodium is correct answer.
• Sodium seems to be a more active catalyst than potassium, and when it reacts with water, it forms sodium hydroxide, a strong base (NaOH).
• To generate sodium halides, salt metal reacts vigorously with all halogens.
• As a result, it interacts with fluorine, F2, chlorine, Cl2, bromine, I2, and iodine, I2 to produce sodium(I) bromide, NaF, sodium(I) chloride, NaCl, sodium(I) bromide, NaBr, and sodium(I) iodide, NaI, respectively.
• Option A) Copper is incorrect answer.
• Because magnesium is more reactive than copper, it can replace copper from a copper sulfate, giving in mgso4.
• Platinum, on the other hand, is less reactive than copper and so is unable to remove copper from a copper sulphate solution.
• Option C) Iron is incorrect answer.
• Iron reacts with a variety of different chemicals, including oxygen, carbon, phosphorus, halogens (bromine, iodine, fluorine, and chlorine), and nitrogen.
• It interacts with a wide range of substances.
• Option D) Magnesium is incorrect answer.
• When magnesium is exposed to oxygen, it forms magnesium oxide.
• Magnesium hydroxide is produced when magnesium is exposed to hydrogen.
• Magnesium nitride is manufactured when magnesium is reacted with nitrogen.
• Magnesium is extremely reactive when treated with halogens.
