Question

Based on the reaction, identify the products.

BeF2 + Mg → MgF2 +

What type of reaction does this represent?


synthesis
replacement
decomposition
combustion

Answer 1

The products of the reaction \( \text{BeF}_2 + \text{Mg} \) are \( \text{MgF}_2 + \text{Be} \).

The balanced reaction is:
\[ \text{BeF}_2 + \text{Mg} \rightarrow \text{MgF}_2 + \text{Be} \]

This represents a **replacement reaction**, specifically a single replacement reaction, where magnesium replaces beryllium in the beryllium fluoride compound.

So, the correct answers are:
- The products: \( \text{MgF}_2 + \text{Be} \)
- Type of reaction: replacement.
