Syllabus · SSLC · Classes 8 to 10

Every chemical formula and equation in the SSLC syllabus.

A Kerala SSLC student meets around 50 chemical formulas and 50 chemical equations between Class 8 and Class 10. Balancing is explained first, in Class 8, before a chemical formula or a chemical equation has been explained at all; writing a formula follows in Class 9.

Class 8, Part I, Chapter IV — Basic Constituents of Matter

The gap. The order is inverted. Balancing an equation is explained in Class 8, before either a chemical formula or a chemical equation has been explained.

Compiled by the author from the board’s own textbooks, chapter by chapter. Equations are recorded as the textbook sets them; where one is printed without being balanced it is marked as such and left as printed. Have a teacher confirm the list against the current edition before it is sent to a school.

Questions

How many chemical formulas and equations are in the Kerala SSLC chemistry syllabus?
About 50 chemical formulas and 50 chemical equations across Classes 8 to 10. The chapter-by-chapter list on this page enumerates each one.
When does the Kerala syllabus teach a student to write a chemical formula?
Class 9. Balancing chemical equations is explained a year earlier, in Class 8, Part I, Chapter IV.
Why is the Class 8 ordering a problem?
Balancing an equation requires being able to write a chemical formula and a chemical equation first. Both are explained after it.

This is the gap the Playbook was written for.

The Language of Chemistry, Playbook® teaches the alphabets first — thirty elements and twenty-five radicals as punch-out tokens — then formulas, then balanced equations, in that order and with a score gate at each step. It is the order the tables above are set in and the order the textbooks explain last.

  • ICSE — Classes 6 to 9 · A student writes symbols in Class 6 and balances equations in Class 8, three years and one year respectively before Class 9 explains valency and how a formula is put together.
  • CBSE — Classes 7 to 10 · Formulas and equations both appear from Class 7. Writing a formula is explained in Class 9 and balancing in Class 10.
