Reactions of Sulfur and Oxygen

The video explains the reaction of sulfur and oxygen to form sulfur dioxide. It describes this as a combination or synthesis reaction, where two reactants combine to form one product. The reaction is also exothermic, releasing energy as heat, and is considered a combustion reaction. The video concludes with a summary of these concepts.

What type of reaction occurs when sulfur and oxygen gas combine to form sulfur dioxide?

• Neutralization reaction

• Displacement reaction

• Combination reaction

• Decomposition reaction

What is the role of oxygen gas in the reaction between sulfur and oxygen?

• It acts as a catalyst

• It is a product of the reaction

• It combines with sulfur to form sulfur dioxide

• It is not involved in the reaction

What does it mean when a reaction is described as exothermic?

• It requires a catalyst

• It releases energy

• It absorbs energy

• It occurs at room temperature

Which of the following best describes the reaction between sulfur and oxygen?

• It is both a combination and a combustion reaction

• It is only a combustion reaction

• It is only a combination reaction

• It is neither a combination nor a combustion reaction

What is the final product formed when sulfur reacts with oxygen gas?

• Sulfur hexafluoride

• Sulfur monoxide

• Sulfur dioxide

• Sulfur trioxide
