Question

When oxygen is available to burn sulfur, sulfur dioxide is produced. Which of the following word equations best represents this reaction?
Responses

sulfur dioxide → sulfur + oxygen gas
sulfur dioxide → sulfur + oxygen gas

sulfur + oxygen gas → sulfur dioxide
sulfur + oxygen gas → sulfur dioxide

sulfur dioxide + oxygen gas → sulfur
sulfur dioxide + oxygen gas → sulfur

sulfur + dioxygen → sulfur dioxide
sulfur + dioxygen → sulfur dioxide

Answer 1

The correct word equation that represents the reaction in which sulfur burns in the presence of oxygen to produce sulfur dioxide is:

**sulfur + oxygen gas → sulfur dioxide**

Therefore, the appropriate response is:

**sulfur + oxygen gas → sulfur dioxide**
