Question | Answer |
what is matter? | anything that takes up space and has mass |
what is matter made up of? | matter is made up of tiny, vibrating particles |
what are the 5 main points of the particle theory? | all matter is made up of tiny particles that: have empty spaces between them are always moving(vibrating) move faster and spread farther apart when heated particles attract each other |
what is a mechanical mixture? | a mixture with diffrent parts that you can see since the particles are divided unevenly |
what is a solution? | a mixture that looks like a single pure substance, but is a uniform mixture of 2 or more pure substances since the particles are divided evenly |
what is a solute? | the part of the solution that dissolves into a solvent |
what is a solvent? | the part of a solution into which the solute(s) dissolve |
what is concentration? | a solution with a large number of solute particles in a given volume of solution |
what is solubility? | is a measure of how much solute can dissolve into a certain solvent to form a saturated solution |
what makes a substance pure? | a pure substance has only one kind of particle |
what does dissolve mean? | to mix one type of matter into another type of matter to form a solution |
what is the universal solvent? why is it known as the universal solvent? | water becuase dissolves more solutes than any other solvent |
what does dilute mean? | a dilute solution is a solution with a small amount of solute particles |
what is the formula for concentration? | mass of solute(grams)/ 100mL of solution |
what is the formula for solubility? | maximum amount of solute dissolved/ 100mL of solvent |
what is the sequence to figure out concentration or solubility? | GRASS (given, required, analysis, solution, statement) |
