This question is incomplete. Luckily, I found the same problem which is shown in the attached picture. To answer the question, we must know how the size and charge affect the lattice energy. The answer is: lattice energy increases with the increasing charge of the ions, and decreasing radius of the atoms.
<em>Therefore, the ranking would be: A < B < C</em>.

Answer:
The final pressure in the container at 0°C is 2.49 atm
Explanation:
We apply the Ideal Gases law to know the global pressure.
We need to know, the moles of each:
P He . V He = moles of He . R . 273K
(1atm . 4L) / R . 273K = moles of He → 0.178 moles
P N₂ . V N₂ = moles of N₂ . R . 273K
(1atm . 6L) / R . 273K = moles of N₂ → 0.268 moles
P Ar . V Ar = moles of Ar . R . 273K
(1atm . 10L) / R . 273K = moles of Ar → 0.446 moles
Total moles: 0.892 moles
P . 8L = 0.892 mol . R . 273K
P = ( 0.892 . R . 273K) / 8L = 2.49 atm
R = 0.082 L.atm/mol.K
Answer:
Zn. + 2 HCl ----------> ZnCl2. + H2
Explanation:
Mass of Zn in mole = 3.27/ 65.38= 0.050010.... mol
Mass of HCl in mole = 3.3/ 73= 0.044....mol
Hence, limiting reagent is HCl
Molar mass of ZnCl2= 136.38g
Let mass of ZnCl2 be x
x = 3.3*136.38÷ 73 = 6.165...
So, the mass of ZnCl2 is 6.17 g
The true ratio of atoms in a molecule or formula unit is called molecular formula
<h3>What is empirical formula?</h3>
This is the simplest formula that shows the ratio of the different atoms present in a compound.
<h3>What is molecular formula?</h3>
This is the formula of a compound which gives the true or actual ratios of the different atoms present in a compound
<h3>What is molar mass?</h3>
The molar mass of a compound is defined as the sum total of the molar masses of the different atoms present in the compound.
<h3>What is percentage composition?</h3>
This gives the proportion of the different atoms present in a compound.
From the above definitions, we can conclude that the correct answer to the question is molecular formula
