identify the missing product in the following acid - base reaction.

• include the coefficient only if it is larger than 1 in the balanced equation.

provide your answer below:
fe(oh)₂ + 2hf → □ +2h₂o

Explanation:

Step1: Analyze acid - base reaction

In an acid - base reaction, metal hydroxide reacts with acid to form salt and water. Here, $Fe(OH)_2$ is a metal hydroxide and $HF$ is an acid.

Step2: Determine salt formation

The metal $Fe^{2 + }$ from $Fe(OH)_2$ combines with the $F^-$ from $HF$. The chemical formula of the salt formed is $FeF_{2}$. The reaction is already balanced as there are 1 Fe, 2 O, 4 H, and 2 F atoms on both sides of the equation.

Answer:

$FeF_{2}$
