more
Concentration is a measure of the amount of solute present in a ______
solvent
Elements are pure substances made up of a single type of ______

Study Notes
- Everything around us is made up of particles, even we ourselves
- Particles can form pure substances, where all particles are identical, or mixtures, where different types of particles are present
- Pure substances can be thought of as exclusive parties with only one type of particle, while mixtures are open parties with various types of particles
- Particle theory helps distinguish between pure substances and mixtures, as in pure substances, particles are identical, while in mixtures, they retain their individual properties
- Homogeneous mixtures are uniformly distributed throughout the mixture, like a well-blended smoothie, where the components cannot be distinguished
- Heterogeneous mixtures, like a bowl of trail mix, have components that are not uniformly distributed and can be easily separated
- Solubility is the ability of a substance to dissolve in a solvent; water is a universal solvent due to its polarity
- Saturated solution is a party that's at full capacity, while an unsaturated solution can still accommodate more guests (solute)
- Concentration is a measure of the amount of solute present in a solvent
- Separation methods include sedimentation, decantation, filtration, evaporation, distillation, and centrifugation
- Elements are pure substances made up of a single type of atom, while compounds are pure substances made up of multiple types of atoms bonded together
- Elements and compounds have unique properties and can be interchangeable
- Particle theory helps explain the behavior of matter around us.
