Answer 2

Word Equations for the Reaction of Sulfur and Magnesium with Oxygen

When sulfur and magnesium react with oxygen, they form oxides. Let's write the word equations for these reactions and identify the products.

1. Reaction of Sulfur with Oxygen: - Word Equation: Sulfur + Oxygen → Sulfur Oxide - Product: Sulfur Oxide

2. Reaction of Magnesium with Oxygen: - Word Equation: Magnesium + Oxygen → Magnesium Oxide - Product: Magnesium Oxide

Character of the Formed Oxides

To determine the character of the formed oxides, we need to consider whether they are acidic, basic, or amphoteric.

1. Sulfur Oxide: The oxide formed from the reaction of sulfur with oxygen is sulfur oxide. Sulfur oxide can refer to different compounds, such as sulfur dioxide (SO2) or sulfur trioxide (SO3). Both sulfur dioxide and sulfur trioxide are acidic oxides. They react with water to form acids, such as sulfuric acid (H2SO4).

2. Magnesium Oxide: The oxide formed from the reaction of magnesium with oxygen is magnesium oxide (MgO). Magnesium oxide is a basic oxide. It reacts with water to form a base, magnesium hydroxide (Mg(OH)2).

To summarize: - The oxide formed from the reaction of sulfur with oxygen is an acidic oxide. - The oxide formed from the reaction of magnesium with oxygen is a basic oxide.

Please note that the specific oxide formed from the reaction of sulfur and magnesium with oxygen may depend on the reaction conditions and the stoichiometry of the reaction.
