Between copper and sodium, which metal is more reactive?

  1. Copper

  2. Sodium

  3. Both are equally reactive

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Reactivity of metal depend on the formation of positive ions by losing electron. Sodium have more tendency to form positive ion than copper. Therefore sodium is more reactive than copper.

So option $B$ is correct

Metals which lose electrons easily are said to be:

  1. less reactive than hydrogen

  2. more reactive than hydrogen

  3. have same reactivity as that of hydrogen

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Metals which lose electrons less readily than hydrogen are said to be less reactive than hydrogen. All metals placed below hydrogen in the reactivity series lose electrons less readily than metals placed above hydrogen.

In nature, metal $A$ is found in a free state while $B$ is found in the form of its compounds. Which will be near to the top of activity series of metals?

  1. $A$
  2. $B$

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The metals at the top of the activity series an so reactive that they are never found in nature as free elements.

Which of the following will replace hydrogen from acids to form salts?
$S, P, Na, Si$

  1. Sulphur

  2. Phosphorus

  3. Sodium

  4. Silicon
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Only those metals which are more reactive than hydrogen, displace hydrogen from acids to form salts and evolve hydrogen gas. Out of the given elements, only $Na$ is a metal which is more reactive than hydrogen.

Metal $A + \ $ Salt solution of $B\rightarrow $ Salt solution of  $A + \ $ Metal $B$
Which one is more reactive among $A$ and $B$?

  1. $A$
  2. $B$

  3. Both are equally reactive

  4. None of the baove
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Metal $A$ displaces metal $B$ from its solution. Hence, it is more reactive than $B$.

Statement 1: Zinc metal will reduce $Cu^{2+}$ in solution.

Statement 2: Zinc is a more active metal than copper.

  1. <p>Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.</p>

  2. <p>Both Statement 1 and Statement 2 are correct but Statement 2 is the correct explanation of Statement 1.</p>

  3. <p>Statement 1 is correct but Statement 2 is not correct.</p>

  4. <p>Statement 1 is not correct but Statement 2 is correct.</p>

  5. Both the Statement 1 and Statement 2 are not correct.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In the activity series of metal $Zn$ is above the $Cu$ metal. So it can easily reduce $Cu^{2+}$ in the solution.

In a solution of lead acetate, a strip of metal Z was dipped. After some time, lead from the solution was deposited at the metal strip. Which is more reactive?

  1. $Z$

  2. Lead

  3. Both have equal reactivity

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

$Z$ is more reactive. It replaced lead from its compound.

Food cans are coated with tin and not with zinc because:

  1. zinc is costlier than tin

  2. zinc has a higher melting point than tin

  3. zinc is more reactive than tin

  4. zinc is less reactive than tin
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Food cans are coated with tin and not with zinc because zinc is above the tin in reactivity series means more reactive than tin and can react with food elements preserved in it.
