Question

Statement 1:
Magnesium burns in air with a dazzling white flame.

Statement 2:
Metal + Water $\to$ Metal oxide + Hydrogen

• A. Statement 1 is true, but statement 2 is false.
• B. Statement 1 is false but statement 2 is true.
• C. Statement 1 and 2 both are true but 2 is not the correct explanation of 1.
• D. Statement 1 and 2 both are true and 2 is the correct explanation of 1.

Answer 1

The correct option is C

Statement 1 and 2 both are true but 2 is not the correct explanation of 1.

Statement 1: Reaction of a metal in air
Metal + Oxygen $\to$ Metal oxide

$Mg\left(s\right)+O_2\to MgO\left(s\right)$
Magnesium burns in air with a dazzling white flame to form magnesium oxide.

Statement 2:
Reaction of a metal in water
Metals react with water to form metal oxide and hydrogen gas.
Metal + Water $\to$ Metal oxide + Hydrogen

Thus, statement 1 and 2 both are correct but statement 2 is not the correct explanation of statement 1.
