A. gas B. solid C. liquid D. plasma Explanation: Diffusion is fastest through gases. The next fastest medium for diffusion is liquid, followed by plasma, and then solids. In chemistry, diffusion is defined as the movement of matter by the random motions of molecules. In a gas or...

Solution will involve molecular orbitals - similar to atomic orbitals - but centred around all of the nuclei in molecule. Each defined by sets of quantum numbers,

Acidic solution - A solution in which the concentration of H3O+ is greater than the concentration of OH- Also, a solution in which pH is less than 7. Anions - negatively-charged ions (meaning they have more electrons than protons due to having gained one or more electrons). Arrhenius base - increases the concentration of OH- ions. Atom - An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atom...
