2.1: Pure Substances and Mixtures. In Chapter 1, we learned that atoms are composed of electrons, protons and neutrons and that the number of protons in the nucleus of an atom (the atomic number) defines the identity of that element. For example, an atom with six protons in its nucleus is a carbon atom; seven protons make s it nitrogen; eight.

Assuming all the $\ce{KClO3}$ decomposed to $\ce{KCl}$ and $\ce{O2}$, calculate the mass percent of $\ce{KClO3}$ in the original mixture." I took the amount of $\ce{O2}$, converted it to moles $\ce{O2}$, then divided it to moles of just O, then divived by 3, bcause for every 3 O (for the 3 in the $\ce{KClO3}$) there is a mole of $\ce{KClO3}$ so.

Like a mixture, solutions can be separated into its original components. However, unlike mixtures, solutions can be separated by evaporation. For example: the water and salt solution will evaporate as the solution is heated. The water will change from liquid to gas as the water-salt solution begins to boil, leaving only the salt behind.

A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. Figure 9.1.1 9.1. 1 : Oil and water do not mix, instead forming two distinct layers called phases. The oil phase is less dense than the water phase, and so.

Distillation is a purification technique for a liquid or a mixture of liquids. We utilize the difference in boiling points of liquids as a basis of separation. The core of a distillation process, is selective evaporation and condensation of particular components. Our overall goal is to evaporate and condense only one component from a mixture.

Molar mass of a chemical is the mass, in grams, one mole that that chemical has. And it usually is in units of grams per mole, or g/mol. So here the molar mass of potassium chloride is 74.55 g/mol, which means that one mole of potassium chloride, 6.022x10^ (23) potassium chlorides, has a mass of 74.55 grams. Hope that helps.

Relating what happens in the fractionating column to the phase diagram. Suppose you boil a mixture with composition C 1. The vapor over the top of the boiling liquid will be richer in the more volatile component, and will have the composition C 2. That vapor now starts to travel up the fractionating column.
