In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. A simple example of this concept is that the empirical formula of sulfur monoxide, or SO, would simply be SO, as is the empirical formula of disulfur dioxide, S...

In chemistry, a non-metal (or non-metal) is a chemical element that mostly lacks metallic attributes. Physically, non-metals tend to have relatively low melting and boiling points, and densities, are mostly brittle if solid, and are usually poor conductors of heat and electricity; chemically, ...
The 9 Units of AP Chemistry These are the fundamental concepts every AP Chemistry syllabus must cover (although not necessarily in this order). Unit 1: Atomic Structure and Properties Moles and molar mass Mass spectroscopy of elements Elemental composition of pure substances ...

Is there any additional guidance as far as question types for AP Chemistry? Chemistry does not have specific question types like Physics and Bio do. Questions 1-3 (long questions) are similar to what will be asked this year. Are AP chemistry students still able to use a calculator? Yes, ...
AP Chemistry FRQ Examples I'll go through the solution process for a sample question of each type so you can get a better idea of what the test will be like.Notice that these questions look complex and overwhelming at first, but if you stay calm and break them down methodically, they do...
