Zinc reacts with NaOH to form the following products:

Options

A. `Na_2ZnO_2` and `H_2`
B. Na and `Zn(OH)_2`
C. `Na_2ZnO_2` and `O_2`
D. `Na_2ZnO_2` and `O_2`

Explanation

To solve the question regarding the reaction between zinc and sodium hydroxide (NaOH), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are zinc (Zn) and sodium hydroxide (NaOH).

### Step 2: Understand the Reaction Type
This is a reaction between a metal (zinc) and a base (sodium hydroxide). Such reactions typically produce a salt and hydrogen gas.

### Step 3: Write the Chemical Equation
When zinc reacts with sodium hydroxide, the products formed are sodium zincate (Na2ZnO2) and hydrogen gas (H2). The balanced chemical equation for this reaction can be written as:

\[ \text{Zn} + 2 \text{NaOH} \rightarrow \text{Na}_2\text{ZnO}_2 + \text{H}_2 \]

### Step 4: Identify the Products
From the balanced equation, we can see that the products of the reaction are:
1. Sodium Zincate (Na2ZnO2)
2. Hydrogen gas (H2)

### Step 5: Conclusion
Thus, when zinc reacts with sodium hydroxide, the products formed are sodium zincate and hydrogen gas.

### Final Answer
The products of the reaction between zinc and NaOH are sodium zincate (Na2ZnO2) and hydrogen gas (H2).
