Vocabulary
Define product
The ending substance, or substances, that is made during a chemical reaction
2 substances have 3 atoms in their repeating atom groups. Two of the atoms in their groups are different but they both share one of the same. Ex. HSO2 and HCL. Do they share the same properties?
No, The properties will likely be different because the repeating groups of atoms that make up each sample are different.
What type of reaction is burning?
Chemical
What three letters are the abbreviation for reaction?
RXN
What are the three states of matter?
Solid, liquid, gas
Define reactant
The starting substance in a chemical reaction
Two reactants are mixed together and form two products. Do the products have the same repeating atom groups as the reactants?
No, the atoms are rearranged.
True or false: When something burns, the particles disappear after the reaction? No steals
False, they just change form
What substance was used to steal the diamond from the museum?
Hydrofluoric acid
Whats the 4th state of matter that isn't often discussed?
Plasma
Define substance
something that is made of all the same atoms or group of atoms
CaS + H2O= CaO + HS
Is this possible?
No, because the sulphur (S) is not in the reactants
Atoms of the reactants dont disappear, they just _______ to form the product.
rearrange
What elements are paired together to create Hydrofluoric acid?
H and F (hydrogen and fluorine)
When molecules move around each other, it is a _______
liquid
Define the Law of Conservation of Matter
Atoms are neither created nor destroyed in a chemical reaction
H20 + HCl= 2HCL + O
Is this possible?
Yes
Double points: The difference between gasoline and hydrogren fuel is that hydrogen does not contain which element?
Carbon
What were the 3 properties of hydrofluoric acid?
Colorless, liquid at room temperature, and smelled nasty, like rotton eggs
When molecules move in place, it is a ______
Solid
In a periodic table, what is labeled up and down and which is labeled side to side
Groups go up and down
Periods go side to side
H6C2O + O6= C2O4 + 3H2O
Is this possible?
Yes
Antoine Lavoisier came up with what?
The law of conservation of matter
Repeating atom groups form separate units called ____________ DOUBLE POINTS
LOTS of energy
