Dalton’s law of partial pressures
States that the total pressure of the mixture is the sum of the partial pressures of each gas component.decomposition reaction
The exact opposite of a combination process. A chemical species breaks down to produce two new chemical
species. The general expression for this reaction is C→A + B.deductive reasoning
Takes a general principle and then draws a specific conclusion from the general concept.dehydration
Chemical reaction that results in a loss of water.dehydrohalogenation
When an alkene is acquired by an alkyl halide during an organic reaction. An example of elimination reaction.density
An expression of the amount of space occupied by a given mass of a substance.derived unit
Combinations of base units.dew point
Temperature needed for water vapor to condense into water.diatomic gas
Where two nitrogen atoms are held together by triple bonds.diffusion
The rate at which two gases mix. Inversely proportional to the density of the gas.dilution
Process requires adding more solvent to the initial concentrated solution.dimensional analysis
A technique that uses the units (dimensions) of the measurement in order to correctly solve problems.disaccharide
Composed of two monosaccharidesdiscontinuous theory of matter
Believed matter was actually finite and not limitless.
