  • What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support

    Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...

  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

  • 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...

Coordination Isomers

Isomers involving exchanges of ligands between complex cation and complex anion of the same compound.

Alkaline Battery

A dry cell in which the electrolyte contains KOH.

Activation Energy

Amount of energy that must be absorbed by reactants in their ground states to reach the transition state so that a reaction can occur. In other words, activation energy is the minimum energy required for a chemical reaction to occur.

Hydrocarbons

Compounds that contain only carbon and hydrogen.

Dilution

Process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent.

yttrium metal

Any of a subgroup of rare-earth elements, of which the cerium and terbium metals comprise the other two subgroups.

Displacement Reactions

Reactions in which one element displaces another from a compound.

 

Mole Fraction

The number of moles of a component of a mixture divided by the total number of moles in the mixture.

 

Shielding Effect

Electrons in filled sets of s , p orbitals between the nucleus and outer shell electrons shield the outer shell electrons somewhat from the effect of protons in the nucleus, also called screening effect.

Rate-determining Step

The slowest step in a mechanism, the step that determines the overall rate of reaction.
