  • Creating Malachite egg

    One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

  • What are Compound Microscopes?

    Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

  • Gas of rotten eggs

    If you happen to break a rotten egg, then you know the smell of hydrogen sulfide, because the stench of the spoiled egg depends on of its presence in rotting protein substances.

  • Use of diamonds

    Diamond is a crystalline modification of pure carbon formed in the deep interior of the Earth, in the upper mantle at depths of more than 80-100 kilometers, at exceptionally high pressure and temperature. It is the most precious stone, the hardest and most wear-resistant mineral, the most...

  • Chemical Safety

    People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...



Most Popular

Alkyl Group

A group of atoms derived from an alkane by the removal of one hydrogen atom.

Equilibrium Constant

A quantity that characterizes the position of equilibrium for a reversible reaction, its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.

Biodegradability

The ability of a substance to be broken down into simpler substances by bacteria.

 

Reaction Ratio

The relative amounts of reactants and products involved in a reaction, maybe the ratio of moles. millimoles, or masses.

 

Anion

A negative ion, an atom or goup of atoms that has gained one or more electrons.

 

Formula

Combination of symbols that indicates the chemical composition of a substance.

 

Electrophile

Positively charged or electron-deficient.

Solubility Product Constant

Equilibrium constant that applies to the dissolution of a slightly soluble compound.

Absolute Entropy (of a substance)

The increase in the entropy of a substance as it goes from a perfectly ordered crystalline form at 0 °K (where its entropy is zero) to the temperature in question.

Entropy is a measure of the “dilution” of thermal energy.

Law of Combining Volumes (Gay-Lussac's Law)

At constant temperature and pressure, the volumes of reacting gases (and any gaseous products) can be expressed as ratios of small whole numbers.
