Atoms Never Vanish
⚛️ What does H₂O actually mean? It means 2 hydrogen atoms and 1 oxygen atom come together! By dragging atoms to build water, carbon dioxide, methane, and ammonia, you'll easily grasp how subscripts show the count. ⚖️ Next come chemical equations! In a chemical reaction, atoms are never created or destroyed, so both sides of the arrow must match. Adjust the coefficients until the table turns green. Balancing methane combustion takes three elements at once, while rusting iron needs 4, 3, and 2. 🧪 Finally, a cool rule: water always forms with 2 hydrogen for every 1 oxygen. Extra atoms without a match just stay left over! Built with code · Remix it to add your own equations!
While Ice Melts
🔬 Ice, water, and steam are all the same substance—only the particles are arranged differently! Solids pack tightly, liquids move around, and gases spread far. The number of particles never changes. 📈 Heating ice doesn't raise the temperature continuously; it pauses at 0 and 100 degrees! That heat is used to pull the particles apart. ⚖️ Closed containers keep the exact same weight, but open ones get lighter as particles escape. Made with code · Remix to add your own substance!
