A white solid formed in the flask.

The liquid changed to a lighter blue.

The flask was tilted over that the liquids were mixed.

The flask was sealed with a stopper.

The total mass of the materials was measured.

Which statement best describes the effect of mixing the two liquids in the experiment?

The properties of the liquids change.

The mass of the liquids increases.

The phase of one of the liquids changes.

The temperature of the liquids decreases.

Which statement best explains the cause of the answer to Part A?

The solid is heavier than the liquids.

One of the reaction products was a gas.

The heat caused the sample to become less dense.

The reaction gave off more heat than was added.

Some of the particles dissolved.

Ms. Jones added vinegar into a container of baking soda during her science class. Bubbles of carbon dioxide gas formed as the vinegar and baking soda mixed together. She put a balloon on top of the container to catch the carbon dioxide gas. Which of these caused a chemical change to happen?

Vinegar and baking soda placed in the same container.

The balloon on top of the container.

An increase in pressure because the gas could not escape.

Heat was applied to the container with vinegar and baking soda.

Which of the following is evidence to support a chemical reaction being made?

Use the information and data table below to answer the following questions. A scientist prepared six different mixtures in glass beakers, as indicated in the data table below. Three of the six mixtures included gray iron filings. Each beaker was tightly covered, labeled, and left undisturbed for several days. After several days, the scientist observed each mixture. He noticed the iron filings in Mixture 4 had turned red. The color change in Mixture 4 indicates that

a possible chemical reaction occurred.

salt has no effect on iron filings.

it must have received heat from a source.
