A flask containing a mixture of CH4(g) and NH3(g)is cooled. At -33.3c a liquid begins to form in the flask. What is the liquid? NH3(g) or CH4(g)

Look up the boiling point of NH3 and CH4. My best educated guess is NH3. (CH4 should be lower than that).

Thank you that was correct.

To determine which gas will condense into a liquid first when the mixture is cooled to -33.3°C, we need to look at their boiling points. The boiling point of ammonia (NH3) is -33.34°C, while the boiling point of methane (CH4) is -161.5°C.

Since the temperature at which the liquid starts to form (-33.3°C) is closer to the boiling point of ammonia (-33.34°C), we can conclude that ammonia gas (NH3) will condense into a liquid first as the mixture is cooled.

Therefore, the liquid formed in the flask would be NH3(l) (liquid ammonia).

To determine which gas will condense into a liquid when the flask is cooled, we need to compare their boiling points.

Methane (CH4) has a boiling point of -161.5°C, while ammonia (NH3) has a boiling point of -33.3°C.

In this case, the temperature provided (-33.3°C) matches the boiling point of ammonia, which suggests that NH3 will condense into a liquid before methane.

Therefore, the liquid that forms in the flask upon cooling is NH3 (ammonia).
