Answer:The correct answer is option 4.
Explanation:
Arrhenius acids are those compounds which gives
ions when dissolved in their aqueous solution.

Arrhenius bases are those compounds which gives
ions when dissolved in their aqueous solution.

are Arrhenius acids because they form
ions in their respective aqueous solution.


Hence, the correct answer is option 4.
Answer:
mol LiCl = 4.83 m
Explanation:
GIven:
Solution of LiCl in water XLiCl = 0.0800
Mol of water in kg = 55.55 mole
Find:
Molality
Computation:
mole fraction = mol LiCl / (mol water + mol LiCl)
0.0800 = mol LiCl / (55.55 mol + mol LiCl)
0.0800 mol LiCl + 4.444 mol = mol LiCl
mol LiCl - 0.0800 mol LiCl = 4.444 mol
0.92 mol LiCl = 4.444 mol
mol LiCl = 4.83 m

Answer:
The volume of the flask is<u> 20.245 litres .</u>
Explanation:
We are given with following information-
-------- 1
where R =
Molar mass of 
The given chemical equation is -
--------- 2
Now , calculation -
Mass of
formed = 118g
Molar mass of
= 
Mole = 
Therefore , moles of
formed = 
From equation 2 , we get to know that ,
2mole
formed from 5 mole 
Therefore ,
mole
formed from
mole 
Moles of
used =
R= 
Pressure (P)= 1.85atm
Temperature (T)= 322K
Moles of
(n)=
moles
Applying the formula above in 1 equation , that is
PV = nRT
putting the given values -

V = 20.245 litres.
Hence , the volume of the flask is <u>20.245 litres . </u>
