SEPARATING HOMOGENEOUS MIXTURE Flashcards
IS COFEE AN EXAMPLE OF HOMOGENOUS MIXTURE?
YES OR NO
YES
TRUE OR FALSE
these solid substances do not necessarily dissolve in one another, physical processes like tumbling and crushing are used to ensure that the components are evenly
distributed ARE CALLED HOMOGENEOUS MIXTURE
FALSE
IT IS A HETEROGENEOUS MIXTURE SINCE NO SUBSTANCE WS DISSOLVED TO ANOTHER
TRUE OR FALSE
Some solids, when mixed together form homogeneous mixtures.
TRUE
_________________is the application of heat to a solid, so it changes to a liquid above a temperature called the melting point.
Melting
WHAT IS THE homogeneous mixtures of metals?
ALLOYS
GIVE OME EXAMPLE OF ALLOYS
Cooking utensils, metal
casings, and some electronic parts are made of alloys too.
It is the process of turning liquids into vapor (gas) by heating.
Evaporation
In this process, a solid and
liquid solution is heated until it boils.
Evaporation
TRUE OR FALSE
Once the solution boils, the liquid solvent starts to evaporate and leaves behind solid solutes.
TRUE
EXPLAIN THE PROCESS OF EVAPORATION
a solid and
liquid solution is heated until it boils.
Once the solution boils, the liquid solvent starts to
evaporate and leaves behind solid solutes.
TRUE OR FALSE
The case for solid solvent and liquid solute separation can also not be done through evaporation.
false
is a separation method wherein a liquid substance changes into a solid
form.
Crystallization
form. It usually happens when the liquid from a solution has evaporated to a point beyond
the solubility limit
Crystallization
is the ability of a substance to dissolve in a given amount of solvent at a specific temperature.
Solubility
true or false
in solubility
Solid crystals will then grow out of the
solution because the solution is too concentrated for all the solids to remain dissolved at that temperature.
true
TRUE OR FALSE
Crystallization is often done from a cold concentrated solution because most substances are more soluble when the liquid is hot
FALSE
TRUE OR FALSE
During Crystallization, cooling it,
crystals form as the solubility gets less and less.
TRUE
is a separation technique that makes use of the difference in boiling points
between two liquids.
Distillation
