The reaction will take place, and the balanced chemical equation is:<br />\[ 2Al + 3KBr \rightarrow 2AlBr_3 + 3K \]

Explicação

## Step 1: Understand the Activity Series<br />The activity series is a list of elements ordered by their reactivity from highest to lowest. It is used to predict the outcomes of single displacement reactions, where one element displaces another in a compound.<br /><br />## Step 2: Identify the Reactants<br />In the given reaction, the reactants are aluminum (Al) and potassium bromide (KBr).<br /><br />## Step 3: Locate the Elements in the Activity Series<br />Find the positions of aluminum (Al) and potassium (K) in the activity series. Aluminum is above potassium, indicating that aluminum is more reactive.<br /><br />## Step 4: Apply the Activity Series to Predict the Reaction<br />Since aluminum is more reactive than potassium, it can displace potassium from potassium bromide (KBr). This means that aluminum will react with potassium bromide.<br /><br />## Step 5: Write the Balanced Chemical Equation<br />The balanced chemical equation for the reaction is:<br />\[ 2Al + 3KBr \rightarrow 2AlBr_3 + 3K \]
