However, mhchem still needs to be added to the MathJax configuration. MathJax has become the de facto standard for displaying mathematics on the Web and since version 2.7 Moodle has a built-in MathJax loader filter. In Moodle 2.8, it is possible to 'have the best of both worlds' by enabling the TeX and MathJax filters in parallel such that the TeX filter (particularly with SVG rendering) provides a fallback for MathJax, and vice versa. The TeX filter typically generates lower quality display (MathJax > SVG > PNG > GIF), though the new SVG output option in Moodle 2.8 approaches the quality of MathJax. After initial loading the TeX filter-generated images are cached, and so quick to display. In these cases, it may be advantageous to use the server-side TeX filter.

Also, there may be conflicts between MathJax and other JavaScript libraries (e.g. on some platforms (especially mobile) or for particularly complex maths/science expressions. However, MathJax rendering depends on client-side JavaScript processing by the browser and may be subject to significant delay, e.g. The first, via MathJax is the simplest to set up and provides high quality rendering. The mhchem package can be integrated with Moodle in one of two ways.

organic chemistry), homologous series and functional groups, you may also wish to consider a 'drawing' plugin such as the MarvinJS-based Chemical structures and reaction editor Installation

This is particularly useful for documenting isotopes, relative atomic and relative molecular mass, empirical and molecular formulae, balanced equations (full and ionic), equilibrium reactions and themodynamics.įor more complex structural and displayed formulae (e.g. In Moodle, mhchem syntax can use text input directly into an HTML editor (TinyMCE or Atto) or by an Atto chemistry plugin (similar to the Atto equation plugin). The mhchem extension allows a more adaptable display and more natural input of chemical formulae and equations. The complexities of supercript and subscript notation, ions and isotopes. Different display conventions: uppercase letters are displayed in italics for mathematics, whereas element symbols are upright for chemistry. However, it is rather cumbersome for a range or reasons.
