Answer:
This means that as pressure increases,the volume decreases or the volume increases as the temperature increases, and decreases as the temperature decreases

Answer: 1:3
Explanation:
1) To state the mole ratio of a product and a reactant we need the chemical equation that shows the reaction.
2) In the case of Fe3O4 and Fe, the chemical equation is:
<span> Fe+H2O → Fe3O4+H2.
3) Now, you balance the equation, which will give you the coefficients of each reactant and product of the chemical reaction:
</span>
<span> 3Fe+4H2O → Fe3O4+4H2
4) From that the mole ratios are:
3 mol Fe : 4 mol 4H2O : 1 mol Fe3O4 : 4 mol H2.
5) The question requires you to find the mole ratio for Fe3O4 to Fe. Tha is:
1 mole Fe3O4 : 3 mole Fe
So, the answer is 1:3

Answer:
Energy released = 
Explanation:
Amount of fissionable material = 2.5 kg
Mass defect = 0.10 % of fissionable material
Mass defect 
Where,
m = Mass defect in Kg
C = Speed of light m/s2
Now substitute the values in the above equation
The expansion work on an irreversible system is equal to:
W = - PV
Assuming that the gas is ideal, therefore:
PV = nRT
[P=pressure, V=volume, n=number of moles, R=gas constant,
T=absolute temperature]
Therefore,
W = -nRT
W = -(1 mol) * (8.314 J / mol K) * (1250 K)
W = -10,392.50 J
Therefore about 10,392.50 J or 10.4 kJ of work is done on
the system.
