A container contains a mixture of hydrogen, oxygen, fluorine, chlorine and nitrogen gases. The pressure of hydrogen is 85.42kPa. The pressure of oxygen is 3.2kPa. The pressure of fluorine is 22.65kPa. The pressure of chlorine is 55.4kPa. The pressure of nitrogen is 65.3kPa. What is the total pressure of the container

 The total pressure of the container is 231.97 kPa.

Explanation:

Given: ,        

,            

Total pressure is the sum of pressure of each component of the gas present in a vessel or container.

Hence, total pressure of the container is calculated as follows.

Thus, we can conclude that the total pressure of the container is 231.97 kPa.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

the answer is d.) potassium
