Which of the following examples shows that a chemical reaction has occurred?
A rock breaks into smaller pieces when it is struck with a hammer.
Rust forms on a hammer that has been left outside too long.
A cup of water turns pink when a few drops of red food coloring are added.
A solid is formed when heat is removed from a sample of water.
A student places a piece of potato into a container of hydrogen peroxide. One observation the student makes is that bubbles form around the potato. The presence of bubbles might indicate the formation of a new substance because bubbles -
could show that a gas is forming

are almost always perfectly spherical.
usually burst after a few minutes.
A clear liquid from a flask is poured into another clear liquid in a beaker. Which of the following results of this procedure would indicate a new substance was formed?
The level of the substance in the beaker is higher after the other liquid is added.
A yellow solid forms and then settles to the bottom of the beaker.
Small white crystals are left behind in the flask that held the first liquid.
Which of the following is an example that includes evidence of a chemical reaction?
A sample of zinc is placed in water and it settles to the bottom.
A solid block of ice is heated and it completely melts into a liquid.
Sugar that is burned gives off an odor and turns brown and then black.
A tomato is placed into a blender and chopped up into smaller pieces.
