Answer:
Explanation:
<u>1) Reaction (given):</u>
<u />
- FeO(s) + CO(g) → CO₂(g) + Fe(s) ΔH = -11.0 kJ;
ΔS = -17.4 J/K
<u />
<u>2) Spontaneous reactions (ΔG < 0)</u>
The sign of the change in free energy (ΔG) tells if a reaction is spontaneous or not at a given temperature and constant pressure.
If ΔG is negative ( ΔG < 0) the reaction is spontaneous; if ΔG is positive ( ΔG > 0) the reaction is nonspontaneous.
Then, determine the temperature at which ΔG becomes zero, which is the temperature at which the reaction becomes nonspontaneous.
<u>3) ΔG⁰ = ΔH⁰ - TΔS⁰</u>
ΔG⁰ = -11,000 J - T (-17.4 J/ K) [ -11.0 kJ were converted to J]
0 = - 11,000 J + 17.4 T J/K
11,000 J = 17.4 T J/ k
T = 11,000 kJ / (17.4 J/K) = 632 K ← answer
Answer:
10.2 moles of oxygen which is 163.1 grams
Explanation:
A. represents a situation in which the person is not handling frustration well. In the other situations, the people found they weren't doing as well as they had hoped and so they actively found ways to maneuver around this to improve their lives. Leslie gave up her job simply the move back with her parents with no indication that she would be able to support herself until she got the job she wanted. It's important to keep a source on income while chasing down a dream job.
Hope this helps! :)
The statement which describes the dependent variable would be the measured variable. We usually use the independent variable and manipulate it and change its levels to see how the levels of the measurable (dependent) variable change.
Magnesium oxide can be very bad for your health, and when we did an experiment with it in class it was white because it was so hot. It is very flammable.
