The correct Answer is:
To solve the question "When boron is fused with NaOH, what products are formed?", we can follow these steps: ### Step 1: Understand the Reaction When boron (B) is fused with sodium hydroxide (NaOH), a chemical reaction occurs. We need to identify the products of this reaction. ### Step 2: Write the Chemical Equation The reaction can be represented as: \[ \text{B} + \text{NaOH} \rightarrow \text{Na}_3\text{BO}_3 + \text{H}_2 \] ### Step 3: Balance the Chemical Equation To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides. 1. **Boron (B)**: There is 1 boron atom on the left and 1 in the product Na3BO3 on the right. 2. **Sodium (Na)**: There are 3 sodium atoms in Na3BO3. Therefore, we need 3 NaOH on the left. 3. **Hydrogen (H)**: Each NaOH contributes 1 hydrogen atom, so 3 NaOH gives 3 hydrogen atoms. Additionally, we need to account for the hydrogen gas (H2) produced. Thus, we need 3 H2 on the right. 4. **Oxygen (O)**: There are 3 oxygen atoms in Na3BO3. The balanced equation becomes: \[ 2\text{B} + 6\text{NaOH} \rightarrow 2\text{Na}_3\text{BO}_3 + 3\text{H}_2 \] ### Step 4: Identify the Products From the balanced equation, we can see that the products formed when boron is fused with NaOH are: - Sodium borate (Na3BO3) - Hydrogen gas (H2) ### Conclusion Thus, the correct answer is that when boron is fused with NaOH, the products formed are sodium borate (Na3BO3) and hydrogen gas (H2). ### Final Answer The products formed are Na3BO3 and H2. ---
