Explanation:

Step1: Determine Reaction Type

The reaction where magnesium combines with oxygen is a combination (synthesis) reaction, as two substances combine to form one. But first, identify reactants and products. Reactants are Mg (magnesium) and O₂ (oxygen, as oxygen exists as O₂ gas). Product is MgO (magnesium oxide, since Mg has a +2 charge and O has -2, so formula MgO).

Step2: Fill Reactants

Reactants are Mg (magnesium) and O₂ (oxygen). So in the reactant tiles: Mg + O₂.

Step3: Fill Products

Product is MgO (magnesium oxide). Since it's a combination reaction, we have MgO. But the product section has two tiles? Wait, no, maybe a typo, but the correct product is MgO. Wait, the reaction is \( 2Mg + O_2
ightarrow 2MgO \), but we don't need to balance. So reactants: Mg and O₂; product: MgO (but if two tiles, maybe one blank? Wait, the choices have a blank tile. Wait, the reaction is Mg + O₂ → MgO (unbalanced). So reactants: Mg + O₂; product: MgO + [blank]? Wait, no, maybe the product is just MgO, but the interface has two tiles. Wait, the correct components:

Reaction Type: Combination (Synthesis)
Reactants: Mg (magnesium) and O₂ (oxygen)
Products: MgO (magnesium oxide) and a blank (since the equation is unbalanced, maybe one product tile and one blank? Or maybe the product is MgO, and the other tile is blank.

So putting it together:

Reaction Type: Combination (Synthesis)
Reactants: Mg + O₂
Products: MgO + [blank]

Answer:

Reaction Type: Combination (Synthesis)
Reactant(s): \( \text{Mg} + \text{O}_2 \)
Product(s): \( \text{MgO} + \) [Blank Tile]

(Note: The choices for reactants are Mg and O₂; for products, MgO and the blank tile. The reaction type is combination (synthesis) as two substances combine to form a new compound.)
