Chemical Change
Concentration of a Solution
100
This is the state of matter where the particles are moving quickly and are far apart from each other.
What is a gas?
100
A change is size, shape or state of matter.
What is a physical change?
100
The type of mixture where some of one type of matter dissolves.
What is a saturated solution?
100
This is the name of the new substance formed in a chemical change.
What is a product?
100
A comparison of two numbers. When talking about solutions, it is the comparison of the volume of solute compared to the volume of solvent.
What is a ratio?
200
This is the state of matter where the particles vibrate and are very close to each other in a set pattern.
What is a solid?
200
These are what are produced in a chemical change.
What are new substances?
200
The part of the solution that makes the other part dissolve.
What is the solvent?
200
This is the name of the original substances in a chemical change.
What are the reactants?
200
A solution that has a low ratio of solute to solvent, weak.
What is dilute?
300
This is the state of matter where the particles are able to slide by each other but do not bounce off each other.
What is a liquid?
300
In a chemical changes, these change.
What is the original substances or types of matter??
300
Three things to make a solute dissolve faster.
What is add mechanical energy (stir), add heat energy and break the solute into smaller pieces?
300
This is the name of a solid that comes out of a solution in a chemical change.
What is a precipitate?
300
The solution that is most concentrated:
24 ml of solute to 100 ml of solvent 14 ml of solute to 50 ml of solvent 10 ml of solute to 25 ml of solvent
What is 10 ml of solute to 25 ml of solvent?
400
When particles gain/absorb heat energy, they do this.
What is move faster and move
farther apart or expand?
400
Milk turning sour is this kind of change
What is a chemical change?
400
A mixture is this type of change.
What is a physical change?
400
This changes color in the presence of a specific reactant.
What is an indicator?
400
Each side of the balance holds 50 ml of a solution made with salt and water. This is the solution that is most concentrated.
What is B?
500
When particles lose/release heat energy, they do this.
What is move slower and move closer together or contract?
500
Oil and vinegar together in a salad dressing is this kind of change
What is a physical change?
500
The reason mixing green food coloring in water is a physical change.
What is no new matter is formed?
500
Five observations that are evidence of a chemical change.
What is fizzing and bubbling, change in heat energy, color change, smoke and ash, and a precipitate forming?
500
Five ways to determine if a solution is more concentrated.
What is stronger odor, stronger taste, darker color, has more mass for the same volume and has a larger ratio?
