Answer:-

Given:-

Magnesium. aluminium, zinc and iron were put in different test tubes containing dilute hydrochloric acid.

To find:-

The fastest rate of reactivity of the following metals.

Let's Learn!

Do you reckon the reactivity series? A brief note here :-

K Pottasiun

Na Sodium

Ca Calcium

Mg Magnesium

Al Alumunium

Zn Zinc

Fe Iron

Sn Tin

Pb Lead

H Hydrogen

Cu Copper

Au Silver

Ag Gold

Pt Platinum

Now, if we move according to the table, the highest reacting metal is Magnesium.

So, Formation of bubbles is fast because it is highly reactive and also, produces bubbles of Hydrogen.

Remember:-

Magnesium does not react with cold water but with hot water, it reacts.

Answer 2

Answer:

Rs. 832.

Step-by-step explanation:

P=Rs.5000, r=8%, t=2

C.I = P[1 - (1+ r/100)t]

C.I = 5000[1 - (1+ 8/100)2]

C.I = Rs. 832.
