Answer:
the neutul atom has the same number of protons in its neclues as positive in its electron cloud#
Explanation:
Answer:
dS= 1.79*169.504
j/k = 303.41 j/k
Explanation:
Fe3O4(s) + 4H2(g) --> 3Fe (s)+ 4H2O(g)
dS(Fe3O4) =146.4 j/k
dS(H2) =130.684
dS(Fe) =27.78
dS(H2O) =188.825
dSrxn = dS[product]-dS[reactants]
= 3*dS(Fe)+ 4*dS(H2O)-[1*dS(Fe3O4)+ 4dS(H2)]
= [3*27.78 +4*188.825-146.4 -4*130.684] j/k = 169.504 j/k
This is the dS for 1mole Fe3O4
for 1.79 mols Fe3O4
dS= 1.79*169.504 j/k = 303.41 j/k
Explanation:
As it is given that both the given containers are at same temperature and pressure, therefore they have the same density.
So, mass of
in container- 1 is as follows.
5.35 mol x molar mass of 
= 7.61 mol x 146.06 g/mol
= 1111.52 g
Therefore, density of
will be calculated as follows.
Density =
density =
= 0.532 g/mL
Now, mass of
in container- 2 is calculated as follows.
4.46 L x 1000 mL/L x 0.532 g/mL
= 2372.72 g
Hence, calculate the moles of moles
present in container 2 as follows.
No. of moles =
=
= 16.24 mol
Since, 1 mol
contains 6 moles F atoms
.
So, 16.24 mol
contains following number of atoms.
=
= 97.46 mol
Thus, we can conclude that moles of F atoms in container 2 are 97.46 mol.
