It all flows from this general principle: as bonds become more polarized, the charges on the atoms become greater, which leads to greater intermolecular attractions, which leads to higher boiling points. There are four major classes of interactions between molecules and they are all different manif...
A double boiler allows chocolate to heat up slowly to a set point and not burn. There’s a lot of sciency stuff behind it, but the basic component is a pot of boiling water underneath a mixing bowl. The water heats up only to 212 degrees Fahrenheit, which is it’s boiling point. T...

Define briefly: a) boiling point. b) melting point. What is the purpose of using the technique called mixed melting point? Why are impurities less likely to crystalize? If crystallized acetylsalicylic acid is not dry, what happens to the melting point?
mineral can be obtained. In this case, the solid material is a mixture of hydrated aluminum oxide and hydrated iron oxide. Hydrated refers towatermolecules that are chemically bound to the two compounds. The chemical formula for aluminum oxide is Al2O3. The formula for iron oxide is Fe2O3...
