The new pressure of the gas would be 505.58 torr
<h3>Boyle's law</h3>
According to Boyle's law, the pressure of a gas is inversely proportional to its volume, provided that the temperature is constant.
This can be mathematically represented as: P1V1 = P2V2
In this case, P1 = 759.4 torr, P2 is what we are looking for, V1 = 97.6 mL, and V2 = 146.6 mL
Hence, P2 = P1V1/V2 = 759.4x97.6/146.6 = 505.58 torr

The number of mole of S₂O₃ produced from the reaction is 13.33 moles
<h3>Balanced equation </h3>
4Sb + 3O₂ —> 2S₂O₃
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles of S₂O₃
<h3>How to determine the mole of S₂O₃ produced </h3>
From the balanced equation above,
3 moles of O₂ reacted to produce 2 moles of S₂O₃.
Therefore,
20 moles of O₂ will react to to produce = (20 × 2) / 3 = 13.33 moles of S₂O₃.
Thus, 13.33 moles of S₂O₃ were obtained from the reaction.

Answer:
A substance that cannot be broken down into another substance by chemical or physical means is called an Element
Answer:
Isopropanol and dichloromethane, distilled well below their boiling point.
Explanation:
The best way to separate isopropanol and dichloromethane is the method of fractional distillation. In this method, different compounds separate from each other due to difference in boiling. The boiling point of dichloromethane is 39.6 degree Celsius which is lower than the boiling point of isopropanol which is 82.5 degree Celsius. So dichloromethane will be evaporated when the temperature reaches to 40 degree Celsius and separated from isopropanol before reaching its boiling point.
