ChemBlocks

Block Coding:

1. Drag elements, molecules, or operators from the toolbox
2. Connect blocks to form chemical equations
3. Click "Run Blocks" to see the generated chemistry code and visualization

Text Coding:

1. Write chemical equations using standard notation
2. Use "+" to combine elements/molecules
3. Use "->" for reactions
4. Click "Run Code" to see visualization

Example:

2H2 + O2 -> 2H2O

This represents the formation of water from hydrogen and oxygen.
