Solids, liquids, and gases are all examples of this.
What is matter?
Melting point, color, and solubility are all examples of these.
What are properties?
When a bath bomb is dropped in water, these appear.
What are gas bubbles?
When new substances are produced from old substances, this is the name of the process.
What is a chemical reaction?
In this kind of system, no matter can get in or out.
What is a closed system?
All matter has mass and takes up this.
What is space?
Density is a ratio of this quantity to volume.
What is mass?
These two bath bomb substances, combined with water, are the only ones that make gas bubbles.
What are citric acid and baking soda?
The same substance is made of this type of particles throughout.
What is the same type?
In an open system, the mass can change if this happens.
What is matter gets in or out?
Everything that is matter is made up of these tiny pieces.
What are particles?
A sample has a mass of 12 g and a volume of 4 cm³. This is its density.
What is 3 g/cm³?
A gas that is non-flammable, at high concentration, will do this to a burning flame.
What is put it out (extinguish it)?
In a chemical reaction, the particles of the old substances do this.
What is break apart and/or join to form new combinations?
Potassium iodide and hydrogen peroxide are mixed in an open container and the mass drops. This is why.
What is a gas formed and escaped?
Joined groups of atoms are called this.
Cutting a sample in half does not change this property, because it is constant for any sample size.
What is density?
The bubbles' gas does not come from gas trapped in the bath bomb. It comes from this.
What is a change to the matter that was already there?
The gas from heated water is made of the same particles as this, so no new substance forms.
What is liquid water?
Reactants with a total mass of 200 g make a gas in a sealed bottle. This is the mass of the bottle after the reaction.
What is 200 g?
The number, type, and arrangement of atoms in a molecule is unique to each one of these.
What is a substance?
Odor is a property determined by this about the atoms that make up a substance.
What are the number, type, and arrangement of the atoms?
When a battery adds energy to water, two different gases form, and all of their matter comes from these.
What are the original water particles?
In a chemical reaction, no new atoms can appear. Atoms are only this.
What is rearranged?
In a closed system the mass stays the same because all of these we started with are still there.
What are atoms?
