Answer 1

Answer:

option b and option d are correct

Answer 2

Statements that are incorrect for magnesium metal are options (b) and option (d).

• Option (a) is correct as magnesium has the ability to burn in the air which results in an intense white flame.
• Option (b) is incorrect as magnesium does not react with cold water at all.
• Option (c) is correct as it reacts with hot water to form magnesium hydroxide and hydrogen gas.
• Option (d) is incorrect as magnesium reacts with chlorine to form ionic chlorides but mgcl2 is an electrolyte.
• Therefore the incorrect statements are options (b) and (d) and correct statements are options (a) and (c).
