Substances and mixtures
This is indicated by showing elemental formula or symbols.
What is a pure substance?
The formula for density.
D=m/V
This is the minor part of a solution.
What is the solute.
This is the smallest unit, and cannot be separated by physical means
What is an Element? (or atom or Compound)
Find the density of an object with a mass of 90g and a Volume of 15mL
What is 6g/mL?
This is the part of a solution which dissolves the other part.
What is a solvent?
CO2 is an example of this.
What is a compound?
Find the mass of a substance with a density of 11.35g/mL and a Volume of 57mL. (state the entire number)
What is 646.95g?
This type of solution will have visible particles on the bottom of the beaker.
What is a saturated solution?
Classify: a magnet pulls 6 grams of iron out of a pile of sand.
What is a mixture (heterogeneous)
If we solve the density equation for volume, it looks like this.
What is V=m/D?
State three factors which increase solubility.
What are, Temperature, stirring, pressure, particle size, or polarity. (3/5 needed)
H on the periodic table is this.
What is an element?
