Chemistry simulations

Chemistry

• Atomic Orbitals: Where is the electron? Look for it again and again, and a shape appears.
• Chemical Reactions: Molecules must crash hard enough to react. What makes that happen more often?
• Combustion: Put a jar over a candle. Why does the flame go out, and when?
• Crystal Growth: Grow a salt crystal on a thread: why does it come out as a neat cube?
• Diffusion: A drop of dye in still jelly: how does it spread with nothing stirring it?
• Electrolysis: Split water into hydrogen and oxygen with a battery. Which gas do you get more of?
• Enzyme Activity: Enzymes speed up reactions. Why do they stop working when it gets too hot?
• Gas Laws: Squash a gas with a piston, or heat it: how does its volume change?
• Molecular Bonding: What holds two atoms together, and how hard do you have to shake them to break it?
• Polymer Chains: Plastics are long chains of small molecules. Why does a chain curl up, and why is it stretchy?
• Radioactive Decay: Unstable atoms break down at random. How can we still say when half of them will be gone?
• Redox Reactions: Two metals and two solutions make a battery. Where do the electrons come from?
• Solutions: How much can you dissolve in a glass of water, and does warming it help?
• States of Matter: Solid, liquid, gas: the same molecules, just jiggling harder.
• pH Scale: Drip acid or alkali into water and watch the colour: how much does each drop change it?
