Answer :
= -1622.8 J/K
= -94.6 J/K
= 0 J/K
Explanation : Given,
= -483.6 kJ
The given chemical reaction is:
First we have to calculate the value of .
Entropy of system = -1622.8 J/K
As we know that:
Entropy of system = -Entropy of surrounding = 1622.8 J/K
and,
Entropy of universe = Entropy of system + Entropy of surrounding
Entropy of universe = -1622.8 J/K + (1622.8 J/K)
Entropy of universe = 0

Answer:Given data from the lab collated as 291.15k for Temperature, 0.061L for volume and 1atm pressure.
Initial hydrogen peroxide solution is 5ml with a weigh % concentration 6.6%
n=0.0025moles of oxygen AND 0.0097moles of H2O2 were present
Explanation:
2H2O2(aq)-----2H2O(I)+2O2(g)
Recall the idea gas equation
PV=nRT
n=PV/RT---(1) solving equation (1) using the data in the answer section above.
n=0.0025moles of oxygen is produced.
Recall that for every 100ml of solution you get 6.6g of hydrogen peroxide.
Your 5ml will thus contain
5ml*6.6g H2O2/100ml=0.33g
no of moles if H2O2=0.33/34.015=0.0097moles
