Front

What is a chemical reaction?

Back

A chemical reaction is a process where substances (reactants) are transformed into new substances (products) through the breaking and forming of chemical bonds.

Front

What are repeating groups of atoms?

Back

Repeating groups of atoms are specific arrangements of atoms that form the basic structural units of a substance, often seen in polymers and other complex molecules.

Front

How do the properties of substances relate to their atomic structure?

Back

The properties of substances, such as smell, color, and state (solid, liquid, gas), are determined by the types and arrangements of atoms in their molecular structure.

Front

What is the significance of the number of atoms in a molecule?

Back

The number of atoms in a molecule can affect its properties; different numbers can lead to different physical and chemical behaviors.

Front

What does it mean for substances to have the same types of atoms?

Back

Substances with the same types of atoms may have similar properties, but their arrangement and number of atoms can lead to different characteristics.

Front

What is the role of a chemist in creating new substances?

Back

A chemist designs and conducts experiments to mix different substances, aiming to create new compounds with desired properties.

Front

What is the difference between a sample and a substance?

Back

A sample is a portion of a substance that is used for analysis or experimentation, while a substance is a form of matter with a specific composition and properties.

Front

How can the state of a substance (solid, liquid, gas) affect its properties?

Back

The state of a substance influences its properties such as density, viscosity, and how it interacts with other substances.

Front

What is the importance of sealing a container during a chemical reaction?

Back

Sealing a container prevents the escape of gases or vapors, ensuring that the reaction occurs under controlled conditions and that all reactants are accounted for.

Front

What is an example of a property that can change during a chemical reaction?

Back

An example of a property that can change is smell; new substances formed in a reaction can have different odors compared to the original reactants.
