You are performing an experiment of combining two substances in a closed container. You first pour 520 mL of a substance followed by 375 mL of substance two. A chemical reaction occurs. Choose the equation below that would best explain the total mass of the combined substances.
520 mL - 375 mL = 145 mL
520 mL x 375 mL = 195,000 mL
520 mL + 375 mL = 895 mL
895 mL - 520 mL = 375 mL

Which describes the particles of a gas?
A gas has a definite shape and a definite volume.
A gas has a definite shape and no definite volume.
A gas has no definite shape and no definite volume.
A gas only has a definite volume.
Which is an example of a physical change?
Ice cream melting
rust on a bicycle
a firework exploding

physical change
Which happens when baking soda mixes with vinegar?
the substances stay the same
a new substance is formed
the baking soda stays the same, but the vinegar changes form
the mixture turns from a liquid into a solid
When heat energy is added to particles, what happens to the particles?
the particles begin to move faster
the particles move much slower than before
all of the particles stay the same even when the heat is added
the particles begin to disappear and there are fewer of them
Changing from one state of matter to another does not involve energy.
true
false
Ms. Meyer ordered a sweet tea from a restaurant. They only had unsweet tea so Ms. Meyer had to add her own sweetener. If she had 240 mL of tea and added 14 mL of sugar to the tea, what would be the mass of her drink?
(you are not including the cup in this measurement)
240 mL because the mass would stay the same
254 mL because each item would keep its own mass and you are combining the two masses together.
226 mL because the 14mL of sugar would dissolve in the liquid
200 mL because some of the tea would be lost in the sugar
