Answer:
6.93
Explanation:
Step 1: Given data
- Standard Gibbs free energy (∆G°): -5.20 kJ
- Equilibrium constant (K): ?
Step 2: Convert the temperature to the Kelvin scale
We will use the following expression.
K = °C + 273.15
K = 50°C + 273.15
K = 323 K
Step 3: Calculate K
We will use the following expression.
∆G° = -R × T × ln K
-5.20 × 10³ J = -(8.314 J/mol.K) × 323 K × ln K
K = 6.93

Answer:
Respiratory System:
Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Answer:
It depends.
Explanation:
Generally, the presence of more landmasses in the Northern Hemisphere produces continental climates with extreme temperatures that are relatively rare in the Southern Hemisphere due to the abundance of oceans at the southern latitudes north of Antarctica.
If a city has average rainfall and warm temperatures in the Northern Hemisphere, it is logical to assume that, on average, a city at the same distance from the equator in the Southern Hemisphere would have slightly cooler temperatures and more rainfall due to the enhanced maritime effect.
This depends, of course, entirely on the local geography of the city in question, and the results could be completely different based on the actual city given.
