I'm doing this now. Include a fire triangle, a small introduction about pure Oxygen, how reactive it is, why substances burn more violently in pure Oxygen than in air, precautions like: wear protective goggles, handle the substances carefully and with large tongs, keep all flammable substances away, don't look directly at the burning substance.

How do chemists explain this difference?

Chemists explain differences in properties or behavior by looking at the molecular structure of substances. Variation in molecular structure can lead to differences in physical, chemical, and biological properties. By understanding how atoms are arranged and interact within molecules, chemists can explain why substances exhibit different characteristics.


Can you provide examples of paramagnetic and diamagnetic substances and explain the differences between them?

Paramagnetic substances are those that are weakly attracted to a magnetic field, such as oxygen and aluminum. Diamagnetic substances, on the other hand, are weakly repelled by a magnetic field, like copper and bismuth. The key difference between them lies in their response to magnetic fields: paramagnetic substances are attracted, while diamagnetic substances are repelled.


Is burning a candle wick a chemical change?

It is a chemical change because you can't put it back together exactly the way it was before. Yes, a chemical change is taking place. Even simple cooking produces chemical changes. The smoke and the temperature change are good signs a chemical change is taking place


What is the word used to explain the behaviour of matter and mixtures?

The word used to explain the behavior of matter and mixtures is "chemistry." Chemistry is the branch of science that studies the composition, structure, properties, and reactions of matter. It explores how substances interact, combine, and transform.


Can you explain the meaning of the expression "like dissolves like"?

The expression "like dissolves like" means that substances with similar chemical properties are more likely to dissolve in each other. This principle is commonly used in chemistry to predict how well different substances will mix together.
