A sample of hydrogen is collected over water at 12 oC. The pressure of the hydrogen and water vapor mixture is 0.2atm. The hydrogen is then cooled, at the same volume, to 0 oC. What is the new pressure?

What type of reaction is shown below? check all that apply. 2h2o2 → 2h2o + o2 synthesis decomposition combustion

What is i fracture in the crust called when land move up, down or sideways

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
