Front

What type of reaction is represented by the equation CH₄ + O₂ → CO₂ + H₂O?

Back

Combustion

Front

How do you balance the equation SeCl₆ + O₂ → SeO₂ + Cl₂?

Back

1, 1, 1, 3

Front

Which of the following is NOT a diatomic molecule: Fluorine, Nitrogen, Boron, Bromine?

Back

Boron

Front

Is the reaction Ag⁺(aq) + Cl⁻(aq) → AgCl(s) a redox reaction?

Back

False

Front

Define a diatomic molecule.

Back

A diatomic molecule is a molecule composed of only two atoms, which can be of the same or different chemical elements.

Front

What is a combustion reaction?

Back

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

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the law of conservation of mass is obeyed, meaning the number of atoms of each element is the same on both sides of the equation.

Front

What are the products of the combustion of methane (CH₄)?

Back

The products are carbon dioxide (CO₂) and water (H₂O).

Front

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.
