:D
:D
What would dissolve the best in water
vinegar
HCI ~APEX
What causes the pressure inside oxygen tanks to change as they are filled
The number of gas molecules changes.
the number of gas molecules changes
What would happen to a sealed bag of chips left in the sun
the bag inside the bag would expand
D:
Which intermolecular force would affect the boiling point the least
Van der Waals forces
Which intermolecular force would affect melting point the most
Hydrogen bonding
Which intermolecular force would cause the highest boiling point
Hydrogen Bonding
How does decreasing the temperature affect the volume of a gas
As indicated by Charles's Law, at constant pressure, the volume decreases when the temperature decreases. This is due to slowed collisions between molecules.
What forms of the ideal gas law would you use to calculate the number of moles of gas
Probable you think to the law of Avogadro.
What is the overall effect adding a solute to a solution
boiling point is increased and freezing point is decreased
What would mix the best with water non polar molecules polar molecules fatty molecules symmetrical molecules
Polar molecules are mixed better with water.
Which molecular solid would have the highest melting point
A solid that has hydrogen bonding would melt the easiest.
Which of the following is an example of a heterogeneous mixture water saltwater dirt or brass
Dirt is a heterogeneous mixture.
What will result from increasing the temperature of gas
Increasing the temperature of gas the volume increase.
