During dissolution in chemistry, the solute breaks down into elementary particles and mixes with the solvent. But this depends on the nature of both solute and solvent, which will be thoroughly discussed in the succeeding sections. To give an overview, a covalent compound (e.g. ammonia, chlorin...
A solid is a state of matter characterized by particles arranged such that their shape and volume are relatively stable. The constituents of a solid tend to be packed together much closer than the particles in agasorliquid. The reason a solid has a rigid shape is that the atoms or molecules...
There are two types of mixtures. They are: i)Homogeneous mixture: It has a uniform or even distribution of constituent particles. ii)Heterogeneous mixture: It has a non-uniform or uneven distribution of constituent particles. What is a mixture in chemistry?
Key Takeaways: Suspension Chemistry Definition A suspension is a type of heterogeneous mixture. Over time, particles in a suspension will settle out. A suspension contains larger particles than are found in a colloid. In a colloid, the particles remain mixed over time. Suspension Definition In c...
mesh - the number of openings per linear inch of a screen; measures size of particles; "a 100 mesh screen"; "100 mesh powdered cellulose" mil - a unit of length equal to one thousandth of an inch; used to specify thickness (e.g., of sheets or wire) pica em, em, pica - a line...

Particle size affects reactivity. For example, a pile of corn starch is relatively inert. If one applies a direct flame to the starch, it's difficult to initiate a combustion reaction. However, if the corn starch is vaporized to make a cloud of particles, itreadily ignites. ...
It uses the concept of selective adsorption as its foundation. The polarity difference between molecules in a mixture is used in chromatography. A liquid is used as the "mobile phase," which moves through a "stationary phase" of particles. The mixture to be separated is first delivered as a...
of energy per temperature per mole while the Boltzmann constant is given in terms of energy per temperature per particle. From a physical standpoint, the gas constant is a proportionality constant that relates the energy scale to the temperature scale for a mole of particles at a given ...
