Chemical Reactions and Equations Explained
A chemical reaction is a process where substances called reactants change into new substances called products, with bonds broken and formed. A chemical equation writes this with formulas and arrows, and it must be balanced so the number of each atom is the same on both sides. A concept map of this topic links the reaction types, the balancing method and the signs that a reaction has happened.
- Reactants and products: starting substances, new substances and the arrow between them
- Reaction types: synthesis, decomposition, single and double displacement, combustion
- Balancing equations: conserving mass by adjusting coefficients, never subscripts
- Signs of reaction: color change, gas, precipitate, temperature change, light
Use the map to revise each reaction type with its example equation, then test balancing skills. CogniGuide can build a personalized version from your own chemistry notes.

Chemical Reaction and Equation FAQs
Common questions about reactions, equations and making your own map.
Why must chemical equations be balanced?
The law of conservation of mass says atoms are neither created nor destroyed in a reaction. A balanced equation shows the same number of each atom on both sides, so the reactants and products account for all matter.
What are the four basic types of chemical reactions?
Synthesis combines substances into one. Decomposition breaks one substance into simpler ones. Single displacement swaps one element with another, and double displacement swaps partners between two compounds.
Which files can I use to make my own chemistry map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or images. The AI turns the content into an interactive mind map.
Can I turn the reaction map into a quiz?
Yes. You can turn any CogniGuide map into a quiz to test yourself on reaction types and balancing. The free plan includes 5 creations a week.
