Question

1.Identify the correct statement from the following:
(a)MnO2 is getting reduced whereas HCl is getting oxidized
(b)MnO2 is getting oxidized whereas HCl is getting reduced.
(c)MnO2 and HCl both are getting reduced.
(d)MnO2 and HCl both are getting oxidized.

2. In the above discussed reaction, what is the nature of MnO2?
(a)Acidic oxide
(b) Basic oxide
(c) Neutral oxide
(d) Amphoteric oxide

3. What will happen if we take dry HCl gas instead of aqueous solution of HCl?
(a)Reaction will occur faster.
(b)Reaction will not occur.
(c)Reaction rate will be slow.
(d)Reaction rate will remain the same.

Answer 1

Answer:

1.) (a.) MnO2 is getting reduced whereas HCl is getting oxidized.

See the 1st pic to understand the equation.

2.) (b.) Basic oxide.

As, Manganese is a metal.

As, Manganese is a metal.And metal oxides are basic oxides.

3.) (b.) Reaction will not occur.

Dry HCl will not dissociate to produce H+ ions thus reaction will not occur. ( See 2nd pic to understand the question's answer).

Hope it helped you..

Thank you !!!!

Answer 2

$\huge\color{purple}{ \colorbox{orange}{\colorbox{white} {ANSWER}}}$

1st answer:-

(a) MnO2 is getting reduced whereas HCl is getting oxidized.

2nd answer:-

(b) Basic oxide

because here Magnesium is base and oxygen is forming the metal oxide.

3rd Answer:-

(b) Reaction will not occur.

Dry HCL will not react to produce H ions..so due to this reaction will not take place.
