Question
I need your help with both, it kind of goes hand in hand
7.) Think about what is happening to molecules in the can as the temperature increases. Tell if the energy flow is exo or endothermic. A can of water (65°C) is heated on a hotplate and turns into steam (105°C) Explain how the arrangement and the motion has changed. B.) Use Dalton's law of partial pressure to calculate the pressure of nitrogen gas in a mixture of oxygen and helium. The total pressure of the gas is 120.0 kPa, the pressure of the oxygen gas is .88 atm and the pressure of the helium is 95 torr. Explore
