including, for example, water, glucose, and proteins. This chapter begins by examining elements and how the structures of atoms, the basic units of matter, determine the characteristics of elements by the number of protons, neutrons, and electrons in the atoms. The chapter then...
absolute error- an expression of the uncertainty or inaccuracy of a measurement. absolute temperature- temperature measured using the Kelvin scale. absolute uncertainty- the uncertainty of a scientific measurement, given in the same units as the measurement. absolute zero- the lowest possible state at...
Any chemistry unit has a conversion factor. If it involves numbers and units and calculations, it will have a conversion factor, either to another unit within the system (kg to g) or from one system of measurement to another (pounds to g).What...
