Document Summary
The prefixes and the values that represent (deci, centi, milli, etc) Conversion, especially 1 inch = 2. 54 cm. Definition of element, compound, homogeneous and heterogeneous mixtures. Drawing orbitals and knowing how many electrons each can hold. Temperature: tf = 1. 8(tc)+32, tk = tc + 273, tc = (tf 32)/1. 8. Scientific notation: a number written in scientific notation has 3 parts, a coefficient, a power of ten, a unit of measurement. 2400 m = 2. 4 x 1000 = 2. 4x10^3 m. Density: the mass and volume of any object can be measured. If we compare the mass of the object to its volume, we obtain a relationship called density. Converting temperature: tf = 1. 8(tc) = 32, temp. Celsius) + 32: tk = tc + 273, temp. Celsius + 273: tc = (tf 32)/1. 8, temp. Fahrenheit 32)/1. 8: measured on the celsius (*c) scale in the metric system, measured on the kelvin (k) scale in the si system.
