Answer:
- 21.3 kJ
Explanation:
For the favorable reaction, ΔG₁ = + 9.2 kJ (ΔG > 0 for unfavorable reaction)
For the favorable reaction, ΔG₂ = - 30.5 kJ (ΔG < 0 for favorable reaction)
For the overall reaction, ΔG = ΔG₁ + ΔG₂ = + 9.2 kJ + (- 30.5 kJ)
ΔG = + 9.2 kJ - 30.5 kJ = - 21.3 kJ

Answer:
negative, positive
Explanation:
A we know that the electrons have a negative charge.
So, when a body has some excess electrons, it means it has negative charge.
When a body has an deficiency of eletrons, it means it gains a positive charge.
An area with excess electrons has a net _<u>negative</u>__ charge; an area with a deficit of electrons has a net _<u>Positive</u>____ charge.
Distance = 2000m
Time = 35 minutes = 35×60 sec = 2100 sec
We know, Speed = Distance/Time
Therefore, Speed
= 2000m/2100s = 20/21 m/s
Answer: 20/21 m/s
