Answer:
Explanation:
The pressure of a gaseous mixture is equal to the sum of the partial pressures of the individual gases:
Σ
The prompt is trying to confuse you, but it actually tells us the pressure of the mixture to be 1 atm, but this can be converted to torr. Furthermore, we are informed only three gases are in the mixture: diatomic nitrogen, diatomic oxygen, and carbon dioxide:
Solve for Po2:
Thus, the partial pressure of diatomic oxygen is 177.707 torr.

6.7 grams of lithium chloride will be produced.
<h3><u>Explanation:</u></h3>Lithium chlorate is LiClO₃ and lithium chloride is LiCl. The reaction is,
2LiClO₃ = 2LiCl +3O₂.
So here, 2 moles of lithium chlorate produces 2 moles of lithium chloride.
Or, one molecule of lithium chlorate will produce one mole of lithium chloride.
Molecular weight of lithium chlorate = = 90.4.
So, 14.3 grams of lithium chlorate has 0.16 moles of lithium chlorate.
Thereby, moles of lithium chloride produced is 0.16 moles.
Molecular weight of lithium chloride = = 42.4 grams.
So weight of lithium chloride produced = = 6.7 grams.
Thus, weight of lithium chloride produced will be 6.7 grams.
