Think of it this way,
Mix Iron and sulphur in a bowl. How do you separate them? Use a magnet right. Yes.
Now, mix the iron and sulphur together but know, heat them up. Let them cool for a while. After that, use a magnet to separate. You cant. This is because the compound (FeS) now has a different property from its original components.
Apply this theory onto salts.
Answer:
C. protons + neutrons
Explanation:
The mass number is defined as the total number of protons and neutrons in an atom.
Answer:
For CMFR:
V = 5286 m³
t = 2.6 hr
For PFR:
V = 529 m³
t = 19 minutes
Explanation:
Find attached for the calculation.
Here we have to get the change of internal energy by the gas due to the 564 kJ work done by the system and addition of 344 kJ heat to the system.
The change of internal energy of the gas during this process is (+) 908 kJ
We know the summation of heat capacity (ΔU) and work done by a system is equivalent to the heat energy (ΔH).
Or, mathematically we may write, ΔU + W = ΔH.
Now the work done by the system (W) is (-) 564 kJ. The negative sign implies the work done by the system to surroundings as per thermodynamics.
The heat added to the gas (ΔH) is (+) 344 kJ. The positive sign indicate the addition of heat to the system.
On plugging the values: ΔU + (-) 564 kJ = (+) 344 kJ
Or, ΔU - 564 kJ = 344 kJ
Or, ΔU = 344 kJ + 564 kJ
Thus the change of internal energy, ΔU = (+) 908 kJ.
