Answer:
Volume occupied by Neon gas is 52.67 L
Explanation:
Using Ideal Gas Equation:
PV = nRT
where
P = pressure exerted by the gas = 57 atm
V = volume occupied = ?
n = number of moles = 115 moles
R = Ideal gas constant = 0.0821 L.atm/K.mol
(R value should be taken according to the units of Temperature,pressure, volume and mole)
T = Temperature = 45 + 273 = 318 K
(For temperature conversion from C to K add 273 to temperature:T + 273)
PV = nRT , So
Put values of T,P,n,R
V = 52.67 L
Volume occupied by 115 moles of Neon gas at 57 atm Pressure and 45 C temperature is 52.67 L
Explanation:
(a) As per the mole concept, one mole of any atom contains
atoms or molecules, that is, Avogadro's number of atoms.
Therefore, 1 mole of
=
molecules
=
molecules
1 mole of
=
molecules
=
molecules
1 mole of
=
molecules
=
molecules
Hence, there are equal number of molecules present in the given atoms.
(b) Mass of each given atom will be calculated as follows.
Mass = no. of moles × molar mass
As one molecule of
contains 2 atoms of hydrogen.
So, mass of 1 mole of
= 
= 2.016 g
mass of 1 mole of
= 
= 31.996 g
mass of 1 mole of
= 
= 37.996 g
Thus, we can conclude that
has the greatest mass.
The answer is d.HCl hope this helps
Over the course of a reaction the energy changes forms, in the beginning it may be used to produce a set of products, but in the end it can produce energy in the form of a combustion reaction.
