1.

Classify the following as a physical or chemical change:   Tearing a piece of paper into 100 pieces.

Answer: Physical change
Explanation:
Tearing a piece of paper into 100 pieces is classified as a physical change because it does not involve any chemical reactions. The paper is still made up of the same material, but its physical form has changed. The bonds between the paper fibers are broken, resulting in smaller pieces of paper, but the chemical composition of the paper itself remains the same.
2.

Classify the following as a physical or chemical change:     Burning a piece of paper.

Answer: Chemical change
Explanation:
Burning a piece of paper is classified as a chemical change because it involves a chemical reaction. During the burning process, the paper undergoes a chemical reaction with oxygen in the air, resulting in the formation of new substances such as ash, smoke, and gases. The original composition of the paper is permanently altered, making it a chemical change rather than a physical change where only the physical properties of the substance would be affected.
3.

Classify the following as a physical or chemical change:    A reaction occurs, and the product(s) is (are) different from what you started with.

Answer: Chemical change
Explanation:
 A reaction occurring and resulting in a product that is different from the starting material indicates a chemical change. In a chemical change, the arrangement of atoms and molecules is altered, leading to the formation of new substances with different chemical properties. This is in contrast to a physical change, where there is no change in the chemical composition of the substances involved.In a physical change, only a change in their physical state or appearance occurs; no chemical reaction occurs.
4.

Classify the following as a physical or chemical change:     Hammering a nail into a piece of wood.

Answer: Physical change
Explanation:
Hammering a nail into a piece of wood is a physical change. The composition and chemical properties of the wood and the nail remain unchanged. The act of hammering only alters the shape and position of the nail within the wood, which is a physical alteration.
5.

Classify the following as a physical or chemical change. Letting the nail rust.

Answer: Chemical change
Explanation:
Letting the nail rust is classified as a chemical change because it involves a chemical reaction. When the iron in the nail reacts with oxygen in the presence of moisture, it forms iron oxide or rust. This reaction changes the composition and properties of the nail, resulting in a new substance being formed.
6.

Classify the following as a physical or chemical change:     You combine two clear liquids, and they turn cloudy white.

Answer: Chemical change
Explanation:
When two clear liquids are mixed and a white substance is formed, it is an example of a chemical change. A chemical change is a change in which one or more new substances are formed, and the original substances are chemically altered.. In this case, the two reactants have undergone a chemical reaction that leads to the formation of a precipitate.
7.

Classify the following as a physical or chemical change:    You put a yellow liquid and a blue liquid together, and they become green.

Answer: Chemical change
Explanation:
The scenario described involves a chemical change. When you mix a yellow liquid and a blue liquid to produce a green liquid, a chemical reaction occurs. The colors change due to the combination of the two substances, indicating that the molecules in the liquids are rearranging, forming new chemical compounds.
8.

Classify the following as a physical or chemical change:    Cutting an apple in half.

Answer: Physical change
Explanation:
Cutting an apple in half is classified as a physical change because it does not alter the chemical composition of the apple. The act of cutting simply separates the apple into two pieces, but the molecules and atoms within the apple remain the same. No new substances are formed as a result of cutting the apple.
9.

Classify the following as a physical or chemical change:     Letting the cut apple sit out and it turns brown.

Answer: Chemical change
Explanation:
When the cut apple is left out and turns brown, it undergoes a chemical change. This is because the browning of the apple is caused by a chemical reaction between the oxygen in the air and the enzymes in the apple. This reaction leads to the formation of a brown pigment called melanin. 
10.

Classify the following as a physical or chemical change:     The formation of gas bubbles.

Answer: Chemical change
Explanation:
The formation of gas bubbles is classified as a chemical change because it involves a chemical reaction. Gas bubbles are typically formed when a substance undergoes a chemical reaction, such as the release of gas as a product of a reaction. This indicates a change in the chemical composition of the substance, making it a chemical change.
