explanation : i learned this recently
I'm pretty sure the answer is... Mass and volume.
Hope this helps (:
Answer:
Acetone will evaporate faster than water
Explanation:
The rate of evaporation of a substance has a lot to do with the intermolecular forces present in the liquid.
Intermolecular forces in acetone are the weak dispersion forces in acetone while hydrogen bonds are the dominant forces in water. Hydrogen bonds lead to strong intermolecular association and prevent quick evaporation of the water. The weak dispersion forces in acetone leads to its easy evaporation.
Answer:
H2 and O2
Explanation:
A coffee cup calorimeter is basically a type of calorimeter that operates at constant pressure. The heat measured in the calorimeter is equal to the change in enthalpy of the reaction.
This type of calorimeter is apt for reactions involving solutions where there is little or no change in volume.
It is not generally applicable to gas phase reactions such as the reaction between H2 and O2.
