PS EOC Review Chemical Bonding and Reactions

Front

What type of bond is formed between calcium (Ca) and nitrogen (N)?

Back

Ionic bond is formed between calcium (Ca) and nitrogen (N) due to the transfer of electrons.

Front

What type of reaction is represented by the equation Fe + Cl₂ → FeCl₃?

Back

This is a synthesis reaction where two or more reactants combine to form a single product.

Front

What is the term for the small number written after an element in a chemical formula, such as in H₂?

Back

Subscript - it indicates the number of atoms of that element in the molecule.

Front

What type of reaction is represented by the equation C₂H₂ + O₂ → CO₂ + H₂O?

Back

This is a combustion reaction, where a hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

How do you balance the equation Sb₂S₃ + O₂ → Sb + SO₂?

Back

The balanced equation is Sb₂S₃ + 3O₂ → 2Sb + 3SO₂.

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the form of light or heat.
