Heya

Here is your answer
⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇⬇

1st ❓ Answer ⚓

The Name of this Anime Series is One Punch Man and The Character name is One Punch Man (AKA Saitama)

2nd ❔ Answer

Yesssss
It's Really So Simple

Hahaha!

So, The Answer is

This are the Laboratory Method

(A) Principle : In the laboratory,methane is prepared by heating a mixture of anhydrous sodium acetate and soda lime (NaOH + CaO)

CH3COONa + NaOH(CaO) --------> CH4 + Na2CO3

Sodium acetate Soda lime Methane

(B) Procedure : Anhydrous sodium acetate and soda lime are taken in the ratio 1:3 by weight and are mixed immediately.The intimate mixture of sodium acetate and soda lime thus prepared is taken in a dry hard glass test tube fitted with a cork through which a delivery tube passes.The hard glass test tube is now heated strongly when methane is evolved.The first part of the evolved gas is allowed to escape to remove the air inside the test tube.Methane thus produced is collected in a gas jar by the downward displacement of water

(C) Purification : Methane thus prepared contains traces of ethylene,acetylene,hydrogen and moisture as impurities.

(I)Acetylene is removed by passing the impure gas through ammoniacal cuprous chloride solution

C2H2 + CuCl2 ----NH3-----------> C2Cu2 + 2HCl

Ans -1→The name of the anime series is one punch man
characters name is one punch man that is saitama.

Ans-2→ A mixture of sodium acetate and soda lime is taken in a hard glass test tube in the ratio of 1:3. The mixture is heated, as a result, methane gas starts to evolve which is passed through the delivery tube. And the gas is collected on gas jar by downward displacement of water.

sodium acetate- CH3COONa
soda lime- CaHNaO2
soda lime is a mixture of calcium hydroxide and sodium hydroxide.
so i think since it consist of NaOH then i dont think it can be used separately to prepare methane.

so as far as i think ur question is wrong.

hope it helps you
