- weigh the grams
- add to the flask
- fill until half full with water, swirl till dissolved
- fill until bottom of meniscus is at volume line, invert to mix
polarity results in
unequal sharing of electrons in a molecular bond
what is matter
anything that has mass and volume
how can components of a mixture be separated by physical means
- evaporation
- filtration
what is solubility
the maximum quality of a substance that will dissolve in a solvent
what is miscible
when there is no apparent limit to the solubility of a substance in another
- components are miscible
what is immiscible
two substances incapable of being mixed together to make a homogeneous mixture
- components are immiscible
how are alloys formed
mixing molten metals and allowing them to solidify
what is a pure substance
all particles have the same properties
what is a mixture
contains more than one particle
are all mixtures solutions
no
why are alloys considered mixtures
each metal mixed has individual properties
what is molarity
molar concentration
