Chemistry (Greek: chemeia) is a science that studies the nature and properties of substances, especially changes that occur between them (chemical reactions).

Chemical equations describe the course of chemical reactions. It contains information about changes in qualitative and quantitative relations between the components of the reaction.

Matching the coefficients of chemical reactions is often complicated process for both beginners and experienced staff.
A similar challenge may be calculating the molar mass of complex molecules such as peptides or nucleotides.


Physicochemical calculators are useful for:

• matching coefficients of chemical reactions
• calculation of molar masses
• conversion of temperatures, pressures and concentrations
• estimating boiling points.
