What is the partial pressure of carbon dioxide in a container that contains 3.63 mol of oxygen, 1.49 mol of nitrogen, and 4.49 m
lana66690 [7]

Answer:

Partial pressure of CO₂ is 406.9 mmHg

Explanation:

To solve the question we should apply the concept of the mole fraction.

Mole fraction = Moles of gas / Total moles

We have the total moles of the mixture, if we have the moles for each gas inside. (3.63 moles of O₂, 1.49 moles of N₂ and 4.49 moles of CO₂)

Total moles = 3.63 mol O₂ + 1.49 mol N₂ + 4.49 mol CO₂ = 9.61 moles

To determiine the partial pressure of CO₂ we apply

Mole fraction of CO₂ → mol of CO₂ / Total moles = P. pressure CO₂ / Total P

Partial pressure of CO₂ = (mol of CO₂ / Total moles) . Total pressure

We replace values: (4.49 moles / 9.61 moles) . 871 mmHg = 406.9 mmHg

Fission and fusion reactions both release energy. However, only fusion reactions
miv72 [106K]
Answer:
<span>D) combine light nuclei
</span>
Explanation:
Fission and fusion both deal with the alteration of atoms in order to produce energy. However, they are actually opposite processes, this is because:
1- Fission occurs when an atomic nucleus is split/divided into two forming two atoms
2- Fusion occurs when two light atomic nuclei combine together to form a single atom.

Hope this helps :)
