What is the process in which atoms rearrange to form new substances?
Chemical function
chemical family
Chemical reaction
Which of the following is defined as, " to change the order or position of something"?
reactant
product
rearrange
model
Which of the following is defined as, "a starting substance that is part of a chemical reaction"?
product
reactant
molecule
atoms
Which of the following is defined as, "an ending substance that is made during a chemical reaction"?
product
reactant
molecules
atoms
Which of the following is BEST defined as, "something that is made of all the same atoms or groups of atoms"?
products
reactants
substances
molecules
True or False: Substances have different properties because they are made of different groups of atoms.
True
False
True or False: During a chemical reaction, atoms do change from one type to another.
True
False
The diagram above shows the repeating groups of atoms that make up two samples. Both samples are red powdery solids at room temperature. Will the other properties of the two samples be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)
The other properties will be different because there are more repeating groups of atoms in Sample 1.
The other properties will be the same because both samples are red at room temperature.
The other properties will be the same because both samples are powdery solids at room temperature.
The other properties will be same because the repeating groups of atoms that make up the two samples are the same.
Can one substance change into another substance? (read carefully)
No, because things can mix, but they can't change into new things
Yes, because new atoms can be created
No, because atoms can not be destroyed
Yes, because atoms can be rearranged.
The diagram above shows the repeating groups of atoms that make up two samples. Both samples are solids at room temperature. Will the other properties of the two samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)
The other properties will likely be different because there are more repeating groups of atoms in Sample 2.
The other properties will likely be different because the repeating groups of atoms that make up the two samples have different numbers of atoms.
The other properties will likely be the same because the repeating groups of atoms that make up the two samples have the same types of atoms.
The other properties will likely be the same because both samples are solids at room temperature.
Andres is a chemist working at a company that makes ink. To make a new kind of ink, Andres mixed two liquid substances together in a sealed container. The diagram above shows the repeating groups of atoms that make up the two starting substances.
After mixing, Andres found two solid substances in the sealed container. (Nothing had escaped.) Which of the diagrams to the left shows the repeating groups of atoms that make up the ending substances?
What is a product (in chemical reactions)?
Something a company will try to sell to you
Also a potato
When the mitosis space-time folds into a tetrahedron flux-capacitor
The substance(s) that are created after a chemical reaction
The diagram above shows the repeating groups of atoms that make up two samples. Both samples are gases at room temperature. Will the other properties of the samples likely be the same or different? (Examples of properties are smell, color, and the temperature at which a substance melts.)
The other properties will likely be the same because the repeating groups of atoms that make up the two samples have the same types of atoms.
The other properties will likely be the same because both samples are gases at room temperature.
The other properties will likely be different because there are more repeating groups of atoms in Sample 1.
The other properties will likely be different because the repeating groups of atoms that make up the two samples have different numbers of atoms.
A chemist mixed two samples together: a brown solid that melts at about 1,300°C and a colorless liquid that melts at about 20°C. She analyzed the results and found two ending substances. One of the ending substances melts at about 250°C. This ending substance is made up of the repeating group of atoms shown above. Which of the diagrams to the left shows the repeating groups of atoms that make up the samples the chemist mixed together?
True or False: In a complete chemical equation, there must be the same number of atoms of each element on the reactants and products side.
True
False
True or False: In a complete balanced chemical equation, there must be the same number of atoms of each element on the reactants and products side.
True
False
In an exothermic reaction, what happens?
Energy is released making the temperature rise.
Energy is absorbed making the temperature drop.
In an endothermic reaction, what happens?
Energy is absorbed making the temperature drop.
Energy is released making the temperature rise.
Where did the oxygen atoms come from that formed the rust in Westfield?
The water
The air
The fertilizer
The pipes
What is this model missing in the before box to make it correct?
It should only have the oxygen and iron atoms in the before box.
It should have 2 iron atoms in the before box instead of just one.
