Bind Flashcard 2nd Nine Weeks Chemistry

Front

What is a decomposition reaction?

Back

A decomposition reaction is a chemical reaction where a single compound breaks down into two or more simpler products. Example: 2H2O → 2H2 + O2.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a chemical reaction where two or more simple substances combine to form a more complex product. Example: 2H2 + O2 → 2H2O.

KCl

Front

What is the significance of the periodic table in chemistry?

Back

The periodic table organizes all known elements based on their atomic number, electron configuration, and recurring chemical properties.

Front

What is an element?

Back

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Each element is made up of atoms with the same number of protons.

Front

What is a compound?

Back

A compound is a substance formed when two or more elements chemically bond together in fixed proportions. Example: Water (H2O) is a compound made of hydrogen and oxygen.

Front

What is the difference between an ionic bond and a covalent bond?

Back

An ionic bond is formed when electrons are transferred from one atom to another, resulting in charged ions. A covalent bond is formed when two atoms share electrons.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction; the total mass of reactants equals the total mass of products.
