In order for a certain reaction to be spontaneous, the change in Gibb's free energy must be negative, that is:
dG < 0
We can calculate dG using:
dG = dH - dS
When we plug in the given values, we see that the sign of dG will never be negative; therefore, the reaction will not be spontaneous under any conditions.
Answer:
You can find the volume of an irregular object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up.
Explanation:
Answer:
0.89 atm is the pressure of the hydrogen gas
Explanation:
We can use the molar fractions to solve this
Sum of molar fractions (hydrogen + water vapor) = 1
Molar fraction = Pressure gas / Total pressure
Molar fraction water vapor = 0.13 atm/1.02 atm = 0.127
1 - 0.127 = 0.873 (Molar fraction H2)
0.873 = Pressure H2 / Total pressure
0.873 = Pressure H2 / 1.02 atm
0.873 . 1.02atm = 0.89 atm
If we remove 2 electrons, the new charge will be positive by 2 units. Hence, the ion is
.
