Consider the reaction: 

3NO (g) ⇆ N2O (g) + NO2 (g) 

What is the expression for Kc for this reaction?

Overall, 80% of the energy used by the body must be eliminated as excess 
thermal energy and needs to be dissipated. The mechanisms of 
elimination are radiation, evaporation of sweat (2 430 𝑘𝐽/𝑘𝑔) evaporation 
from the lungs (38 kJ/h), conduction, and convection. A person working 
out in a gym has a metabolic rate of 2 500 kJ/h. His body temperature is 
37°C, and the outside temperature 24°C. Assume the skin has an area of 
2.0 m2 and emissivity of 0.97. 
a) At what rate is his excess thermal energy dissipated by 
radiation? (4 marks)
b) If he eliminates 0.40 kg of perspiration during that hour, at what 
rate is thermal energy dissipated by evaporation of sweat?
c) At what rate is energy eliminated by evaporation from the lungs?
d) At what rate must the remaining excess energy be eliminated 
through conduction and convection? (4 marks)

 A 0.2121 g sample of an organic compound was burned in a stream of oxygen, and 
the CO2 produced was collected in a solution of barium hydroxide. 
Calculate the percentage of carbon in the sample if 0.6006 g of BaCO3 was formed.

Consider the following reversible chemical reaction. Imagine that you have prepared a solution of which is initially blood red in color. Answer the following questions in the equilibrium shifts and color changes that result from various chemical changes.

+ +   

      ↑                  ↑                        ↑

   yellow         colorless            blood red

1. First, several drops of concentrated iron nitrate are added to the red solution as a result, the solution will  

2. You know that the iron (III) ions will combine with the chloride ions to form an insoluble salt that precipitates out of solution. If you add a scoop of sodium chloride (NaCI) to the solution, it will

3. Now a milliliter of concentrated potassium nitrate (KSCN) solution is added to the solution, making it 

4. You know that silver ions () will combine with thiocyanate ions (SCN) to form an insoluble salt (AgSCN) that precipitates out of solution. If you add silver ions to this solution, it will

5. You also know that this is an endothermic reaction. If you heat this solution to raise the temperature, it will
