Can you show a picture so I can help??? :)
Answer:
Explanation:
<u>1. Energy to heat the liquid water from 55ºC to 100ºC</u>
<u>2. Energy to change the liquid to steam at 100ºC</u>
- n = 10.1g / 18.015g/mol = 0.5606mol
<u>3. Total energy</u>
Answer:
You should not use an open flame to heat the solvent and the solvent should be heat in a stoppered flask to vapour away from the open flame
Explanation:
I think the correct answer would be the first option. As the hiker reaches the top of the mountain, the plastic bag would, most likely, expand. Before starting, the plastic bag would have a certain amount of gas particles inside. As the you hike, the pressure would decrease causing for the gas molecules to reestablish equilibrium thus pushing the bag outwards. In other words, expanding the bag. Also, base from the ideal gas equation, PV = nRT, at constant temperature and number of moles, pressure and volume are inversely related. Thus, as the pressure decreases, the volume of the system would increase accordingly.
