GCSE chemistry formulas and equations for Zoom and Skype online tuition

When doing tuition using an online platform like Zoom or Skype, you often need to put formulas into the chat box or onto an online whiteboard that wasn’t designed for scientific use and doesn’t support constructing superscript and subscript characters. Also, you may need to write out formulas very quickly if your student asks something unexpected.

So this is a list of a huge number of formulas for the major GCSE and iGCSE chemistry courses using the Unicode superscript and subscript characters, indexed and ready to go for tuition. (For other countries, it should be suitable for tuition of students up to around age 16.)

Covering thirteen pages, sections include:

• common ions
• organic chemistry: combustion, alkene hydration, alcohol oxidation
• acid-base: acids with metals, carbonates, oxides, hydroxides, ammonia reactions
• common reversible reactions: Haber process, syngas, the Contact process
• inorganic reactions: thermal decomposition of calcium carbonate, electrolysis (water, sodium chloride, copper sulfate with graphite or copper electrodes), displacement, thermite, metals reacting with oxygen and water, halogen displacement, both with overall and ionic and half-equations)
• the chemical tests: precipitation, hydroxide tests
• the chemical reactions of biology: respiration and photosynthesis
• core maths equations that might be needed in science, such as area of a circle, volume of a sphere, volume of a cylinder etc.
• some prebuilt unit conversions

Versions of important equations are included in multiple forms, such as with or without state symbols, so you can select one that matches the level you’re working at with the student and keep the lesson flowing.

I’ve used these formulas for a huge number of paid tuition jobs, and couldn’t do anything without them-they’ve really helped me make things clear to students, keep lessons moving and give a professional impression. Many students have asked me how I make equations appear looking good in the chat of a call, or even asked me for this document to use themselves!

The document is an editable rtf and docx file with the equations and all the superscripts and subscripts and some common symbols at the start. You can build your own equations if you need them or edit or reorganise the document to suit your way of working.
