Question

6 fill in the blank 1 point use the activity series of metals to decide if a reaction will occur. k(s) + nabr(aq) → choose your answer...

Explanation:

Step1: Recall the activity series of metals

The activity series of metals is \(K>Na>Li>Ca>Mg>Al>Zn>Fe>Sn>Pb>(H)>Cu>Hg>Ag>Pt>Au\).

Step2: Compare the reactivity of \(K\) and \(Na\)

Since \(K\) (potassium) is more reactive than \(Na\) (sodium) according to the activity series of metals.

Step3: Determine the reaction possibility

A more reactive metal (\(K\)) can displace a less reactive metal (\(Na\)) from its compound (\(NaBr\)). The reaction is \(2K(s)+2NaBr(aq) = 2KBr(aq)+2Na(s)\).

Answer:

Reaction occurs.
