A liquid with something dissolved in it
HCI (Hydrochloric acid)
The molecules of a dissolved substance are surrounded by water molecules and are not visible as separate substances.
The solution is absorbed onto a piece of paper
Increase the pressure of the gas inside
The solute can re-form as a solid.
concentration
Apex - It makes the water molecules bump into the solute more. ^.^
the tendency of liquids to form a vapor
Probable you think to the law of Avogadro.
The volume doubles
A solid that has hydrogen bonding would melt the easiest.
Dirt is a heterogeneous mixture.
In this case the freezing point is lowered.
NaCl
convert the .2 kg of NaCl to moles of NaCl.
A base contain the hydroxyl group (OH)-.
distillation (simple distillation)
A homogeneous mixture
The answer is "Ions in water" on Apex
