Which statement describes an action that most likely resulted in a chemical reaction?
A. A pan of water was heated on a stove, and steam formed.
B. A liquid was mixed with another liquid, and a precipitate formed.
C. A liquid was sprayed into the air, and a sweet odor was smelled.
D. A child blew through a wand filled with soap, and bubbles were produced.
Which of these observations is an indication that a chemical reaction has occurred?
The vinegar took the shape of the container in step 1.
The steel wool sank into the vinegar in step 3.
The temperature of the vinegar increase during step 4.
The steel wool changed shape during step 6.
Based on these observations, which statement contains the best evidence that a chemical reaction occurred?
There is a change in shape.
There is a change in volume.
The two liquids mix into a solution.
The two liquids form a new substance.
Two solutions are mixed and react to produce the solid precipitate AgCl. The chemical reaction is shown by the balanced chemical equation: AgNO3+NaCl→AgCl+NaNO3 . What happens to the total mass as the reaction takes place?
The mass increases.
The mass decreases.
The mass remains constant.
The mass first decreases and then increases.
Which statement best describes evidence that a chemical reaction occurs as a cake bakes?
The water in the cake batter evaporates.
The cake rises as gas bubbles form in the baking cake.
The cake takes the shape of the container in which it is baked.
The water in the cake batter is used to keep the cake moist as it bakes.
