Answer:
The answer to your question is Single replacement
Explanation:
Data
Chemical reaction
Na + H₂O ⇒ NaOH + H₂
Single replacement is a chemical reaction in which a metal replaces the cation of a compound.
Decomposition is a chemical reaction in which a compound forms 2 or more products.
Double replacement in this chemical reaction two compounds react interchanging their cations and anions.
Combustion in this chemical reaction the reactants must be a compound with carbon and the other oxygen and the products must be carbon dioxide and water.
<span>carbon + oxygen → carbon dioxide</span>
Hey there!
Your answer is B. MgCl.
This is because this isn't an actual existing compound.
Water (H₂O) and magnesium chloride (MgCl₂) are both real compounds, but the number of electrons does not line up to make MgCl possible.
Hope this helps!
