Answer:
Because electron mass is so insignificant compared to proton and neutron mass that it can be ignored.
Explanation:
Answer:
1: At temperatures below 542.55 K
2: At temperatures above 660 K
Explanation:
Hello there!
In this case, according to the thermodynamic definition of the Gibbs free energy, it is possible to write the following expression:
![\Delta G=\Delta H-T\Delta S](https://tex.z-dn.net/?f=%5CDelta%20G%3D%5CDelta%20H-T%5CDelta%20S)
Whereas ΔG=0 for the spontaneous transition. In such a way, we proceed as follows:
1:
![0=\Delta H-T\Delta S\\\\T=\frac{-102kJ/mol}{-0.188kJ/mol-K} \\\\T=542.55K](https://tex.z-dn.net/?f=0%3D%5CDelta%20H-T%5CDelta%20S%5C%5C%5C%5CT%3D%5Cfrac%7B-102kJ%2Fmol%7D%7B-0.188kJ%2Fmol-K%7D%20%5C%5C%5C%5CT%3D542.55K)
It means that at temperatures lower than 542.55 K the reaction will be spontaneous.
2:
![0=\Delta H-T\Delta S\\\\T=\frac{132kJ/mol}{0.200kJ/mol-K} \\\\T=660K](https://tex.z-dn.net/?f=0%3D%5CDelta%20H-T%5CDelta%20S%5C%5C%5C%5CT%3D%5Cfrac%7B132kJ%2Fmol%7D%7B0.200kJ%2Fmol-K%7D%20%5C%5C%5C%5CT%3D660K)
It means that at temperatures higher than 660 K the reaction will be spontaneous.
Best regards!
Answer:
25.2 grams HOAc
Explanation:
For solution preparations a simple formula for determining amount of solute needed is ...
from solid stock => grams = Molarity x Volume (Liters) x formula wt of solute
∴ grams HOAc = M·V·f.wt = (0.839M)(0.500L)(60.05g/mol) = 25.2 grams HOAc
Mixing => Transfer gram wt of solute to mixing container and dilute up to but not to exceed total needed volume.
