Question

Hey guyz..!! plzz help me in the question instantly. ..
What is meant by the reactivity series of metals? Explain with example.

Answer 1

Holla ^_^

☸ Required Answer is ⬇ ⬇⬇ ⬇

⭕Reactivity Series of Metals ◾This is a series in which metals are arranged in such a way according to their reactive powers with others metals.

☯ As we move from bottom to top the reactivity of metals increases. Bcz thr metals presents on top can easily loose electrons in comparison to bottom metals. Like ⬇⬇

◾Li (Lithium)

◾K (Potassium)

◾Sr (Strontium)

◾Ca (Calcium)

◾Na ( Sodium)

◾Mg (Magnesium)

◾Al (Aluminium)

◾C (Carbon)

◾Mn (Mangenese)

◾Zn (Zinc)

◾Cr (Chromium)

◾Fe (Iron)
◾.
◾.
◾.
◾.
◾Au (Gold)

eg;-

1◾ 2Na(S) + 2 H2O(I)----- 2 NaOh(aq) + H2(g)

2◾ Fe(S)+ H2So4(I) ----- FeSo4(aq) + H2(g)

Answer 2

Hey !!!! ^_^


Here is your answer

⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️

THE arrangements of metal in a vertical column in order of their decreasing reactivity is called reactivity series of metal .. ..

Just Like ....


Most ⬇️to less ..


1) K (potassium)

2) Na (sodium )

3)Ca(calcium)

4)Al(aluminum)

5) Zn(zinc)

6) Fe(Iron)

7) Sn(tin)

8) Pb(lead)

9) H (hydrogen)

10) CU(copper)

11) Ag(silver)

12)Au(gold)

13) Pt(platinum)

..............

This reactivity series are needed when displacement reaction occurred ...

On that Time More reactive element replace less reactive element ..

As For example ..

ZnO + HCl ------> ZnCl2 + H2O

Zn replace H (hydrogen) and itself combined with Chlorine (Cl)
