Gases unlike the solid and liquid can be compressed into smaller volumes ii. Accuracy is how close the measured value is to the actual value They learn the law of conservation of mass, the law of definite proportions, and the law of multiple proportions.
Liquid samples can be sandwiched between two plates of a salt commonly sodium chlorideor common salt, although a number of other salts such as potassium bromide or calcium fluoride are also used.
Unit 10 — Mixtures and Solutions This unit discusses heterogeneous and homogeneous mixtures, as well as concentration as percent by mass, percent by volume, molarity, dilution of molar solutions, molality, and mole fractions. Tests with Answer Keys, from Bob Bruner.
For example, if the sample is a dilute solute dissolved in water in a beaker, then a good reference measurement might be to measure pure water in the same beaker.
This step controls for a number of variables, e. Unit 3 - Atomic Theory In this unit students study atomic theory. Heat is the transfer of energy due to a difference in temperatures More elaborate methods, such as a "two-beam" setup see figurecan correct for these types of effects to give very accurate results.
Unit 25 - Organic Molecules In this unit students explore the properties of organic molecules.
