If we place a flame in the flask and the flame is extinguished, what does that tell us about the gas's flammability?
The gas is not flammable
The gas is flammable
The gas is oxygen
The gas is propane
If we place a flame in a flask and the flame increases, what does that tell us about the gas's flammability?
The gas is not flammable
The gas is flammable.
The gas is methane
The gas is carbon dioxide.
When the bath bomb creates the fizz, is that fizz new matter?
No but it is a new substance.
Yes new matter and substance.
Which of these could be the bath bomb gas?
methane
oxygen
helium
carbon dioxide
What is matter?
Something that takes up space and has mass.
Something that is energy
Something with mass
Something you can see.
The bubbles produced by the bath bomb is a result of what?
A Chemical Reaction
Matter being Created
Gas that was trapped in the bath bomb
Who cares it's just needs to look pretty
Which describes solubility best?
how well a substance can change into a liquid
how well a substance can dissolve in a liquid
Which are considered evidence that carbon dioxide gas is produced when a bath bomb is added to water?
Select all that apply.
The gas extinguishes a flame.
The gas does not extinguish a flame.
The gas is less dense than air.
The gas is more dense than air.
How can particles of a new substance be formed out of particles of an old substance?
Particles may break apart and rejoin in different ways, forming a substance with a new identity.
Particles get smashed up and disappear, and new particles pop up.

bath bomb
Bath bombs are placed into a bottle with water and sealed up - bubbles of gas appear in the closed system. Where is the gas coming from?
completely new matter that somehow just appeared
matter that was already inside the closed system
a leak in the closed system bottle
What are molecules made of?

Does this show a chemical reaction? Does this follow LOCOM?
Yes, Yes
Yes, No
No, Yes
No, No
If a gas is more dense than than the air around it, the gas will
sink
float
do nothing
What happens to the mass of the system, when a gas is formed in a chemical reaction in a open system?
mass increases-the matter in the gas is added to the system and wasn't there before
mass decreases-the gas can leave the system
mass stays the same
A nonflammable gas is in a flask. A flame is placed ABOVE and is extinguished. How does this relate to the density of the gas?
The gas is less dense since it sinks to extinguish the flame.
The gas is more dense since it rises to extinguish the flame.
The gas is less dense since it rises to extinguish the flame.
The gas is more dense since it sinks to extinguish the flame.
