What do these two changes have in common? chemicals in a battery reacting to power a flashlight an old sandwich rotting in a trashcan

[ "Both are chemical changes.", "Both are only physical changes.", "Both are caused by cooling.", "Both are caused by heating." ]

A

Step 1: Think about each change. Chemicals in a battery reacting to power a flashlight is a chemical change. When the flashlight is turned on, the chemicals in the battery react with each other to form new chemicals. This creates electricity, which powers the lightbulb. A sandwich rotting is a chemical change. The matter in the sandwich breaks down and slowly turns into a different type of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.

D

P is the symbol for phosphorus. According to the legend, phosphorus atoms are shown in orange. H is the symbol for hydrogen. According to the legend, hydrogen atoms are shown in light gray. This ball-and-stick model shows a molecule with one phosphorus atom and three hydrogen atoms. The chemical formula will contain the symbols P and H. There is one phosphorus atom, so P will not have a subscript. There are three hydrogen atoms, so H will have a subscript of 3. The correct formula is PH3. The diagram below shows how each part of the chemical formula matches with each part of the model above.

What do these two changes have in common? a piece of pear turning brown salt and vinegar removing tarnish from a penny

[ "Both are only physical changes.", "Both are caused by heating.", "Both are caused by cooling.", "Both are chemical changes." ]

D

Step 1: Think about each change. A piece of a pear turning brown is a chemical change. The substances in the pear react with oxygen in the air and turn into a different type of matter. If you scrape off the brown part of the pear, the inside will still be white. The inside hasn't touched the air. So the chemical change hasn't happened to that part of the pear. Salt and vinegar removing tarnish from a penny is a chemical change. The salt and vinegar change the tarnish into a different type of matter that can be easily wiped away. This makes the penny look shiny again. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.
