particle model
the three states of matter
what are solid, liquid, and gas?
this creates bubbles & colors the water a different color when combined with it
What is a bath bomb?
a characteristic, quality, or trait used to describe, identify, or classify matter and materials
property
a characteristic that does not change for a substance
what is a property?
the tool you use to measure volume
What is a graduated cylinder?
the name for the smallest piece of matter that cannot be divided or destroyed
What is an atom?
this did not change in a closed system, but decreased in an open system
What is mass?
matter that has a specific, consistent set of properties and is made of the same type of particles (atoms or molecules) throughout
substance
the density of the bath bomb gas compared to air
what is more dense?
the tool you use to measure mass
What is a scale?
difference between melting point vs boiling point
melting point= how fast from a solid to liquid
boiling point= how fast from a liquid to a gas
the two ingredients that reacted to produce the reaction
What are citric acid and baking soda?
A substance that can dissolve in a liquid
soluble
How would you describe the flammability of the bath bomb gas
What is non-flammable?
More dense things do this; less dense things do this (have both answers written)
What is sink; float?
Everything in the universe are made of these
What are particles/atoms/molecules?
How do you know the bath bomb gas cannot be baking soda, citric acid, or water for this reason?
A chemical reaction transforms these starting ingredients into an entirely new substance
a physical combination of two or more substances
mixture
Name a gas that is less dense than air and a gas that is more dense than air
Helium or Neon = less
Carbon Dioxide, Nitrogen, or Argon = more
the law of conservation of matter states that matter cannot do this (2 things)
What is be created or destroyed?
While a physical change (like boiling water) spreads particles apart, this happens to the particles during a chemical reaction.
What is they break apart and rearrange to form entirely new molecules/substances? [1, 2]
The gas that the interaction between the bath bomb and water is...
What is Carbon Dioxide?
a material that cannot dissolve significantly in a particular solvent
insoluble
The scientific name for smell is the property of this.
What is odor?
How does the mass of a system change before and after a reaction in a closed container versus an open container?
In a closed system, mass stays constant because gas cannot escape; in an open system, mass decreases once gas is allowed to escape
