Density
This is the formula to calculate density.
D = m/v
Salt is _____ in water.
Soluble
The bond found in H2
Single bond
Columns in the periodic table have these in common.
chemical properties
My favorite example of an emulsifier (used in cooking)
egg
Water has a density of 1.00 g/mL. An object that sinks in water will have this property.
Density > 1 g/mL
Water and oil are ________
immiscible
The bond found in O2
double bond
The group on the periodic table that reacts violently with water
alkali metals
The term used to describe a solution that has the maximum amount of solute dissolved
Saturated
You can make an object less dense by doing this.
A _________ is the medium you dissolve the solute in.
solvent
The bond found in N2
Triple bond
The periodic table provides these three things about an element.
chemical symbol, atomic weight, atomic number (protons)
extended structure
You can use this procedure to measure the volume of irregularly shaped objects.
Displacement
Two objects have similar densities but form two distinct layers because they are _______
insoluble/immiscible
This is almost always the central atom and will rarely have lone pairs
Carbon
The gaps in the earliest version of the periodic table indicated this.
Undiscovered elements
This type of solution has been heated and extra solute has been added, but dissolves completely.
Supersaturated
Place the states of matter in order of INCREASING density
gas < liquid < solid
A solution will no longer dissolve more solute. You can do this to make more solute dissolve.
Heat or add more solvent
This explains why two compounds that have the same number of atoms and elements would have different chemical properties
arrangement of atoms
Rows in the periodic table have this in common
Energy levels
This is the main reason solutes are miscible/soluble in solvents.
Polarity
