The smallest (most basic) piece of matter
What is an atom?
H2O
What is two hydrogen atoms and one oxygen atom?
The process by which new substances (different than those at the beginning) are formed
What is a chemical reaction?
The molecule that is shown on Board #1
What is carbon dioxide (CO2)?
A vague term to describe a small piece of matter
What is a particle?
Connections between atoms are key to forming this
What is a molecule?
CH4
What is one carbon atom and four hydrogen atoms?
A sign that a chemical reaction is happening
What is (any of the following): bubbles, fizzing, temperature change, and/or new state of matter forming?
The molecule that is shown on Board #2
What is water (H2O)?
Two or more atoms connect in a specific way to form these
What are molecules?
The second half of a chemical equation, the 'stuff' that is being produced
What are the products?
C2H4O2
What is two carbon atoms, four hydrogen atoms, and two oxygen atoms?
What the atoms in molecules have to do in order to be able to rearrange
What is break their connections with the other atoms?
The molecule that is shown on Board #3
What is oxygen gas (O2)?
This thing is modeled by drawing a single circle
What is a particle?
The first part of a chemical equation, that 'stuff' that will be reacting
What are the reactants?
NaHCO3
What is one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms?
The mass of a closed system...
What is never changes?
The molecule that is shown on Board #4
What is sodium chloride / salt (NaCl)?
This thing is modeled by drawing many circles that are connected with lines in between them
What is a molecule?
From hydrogen all the way to oganesson, there are 118 of these different types of atoms
What are elements?
2CO2
What is a total of two carbon atoms and four oxygen atoms (1 and 2 for one molecule)?
All atoms that make up the reactants go towards making this
What is a new combination to make the products?
The molecule that is shown on Board #5
What is sodium bicarbonate / baking soda (NaHCO3)?
One of the main focuses of this unit (we have moved beyond particles!)
What is a molecule!!!
