Answer:
Option ( 1 )
Explanation:
This atom has a cub close pack structure, and therefore - the number of edge center present in X atoms = 4,
Number of unit cells present in X atoms = 6
____________________________________________________
Now the 6th coordination number of X atom = 6 * 4 = 24,
So respectively, the 3rd coordination number of X = 8 -
And thus the ratio between the 6th coordination number and the 3rd coordination number = 24 / 8 = 3,

C. Weak acid is the correct answer
Answer:
V = 240.79 L
Explanation:
Given data:
Volume of butane = ?
Temperature = 293°C
Pressure = 10.934 Kpa
Mass of butane = 33.25 g
Solution:
Number of moles of butane:
Number of moles = mass/ molar mass
Number of moles = 33.25 g/ 58.12 g/mol
Number of mole s= 0.57 mol
Now we will convert the temperature and pressure units.
293 +273 = 566 K
Pressure = 10.934/101 = 0.11 atm
Volume of butane:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
V = nRT/P
V = 0.57 mol × 0.0821 atm.L/ mol.K ×566 K / 0.11 atm
V = 26.49 L/0.11
V = 240.79 L
When two atoms of Hydrogen combine together, or fuse, they make an atom of Helium.
