Question

use the following balanced equation to answer the questions: 4k + o₂ → 2k₂o how many molecules of potassium are present?

Explanation:

Step1: Identify the coefficient of K

In the balanced equation \(4K + O_{2}
ightarrow2K_{2}O\), the coefficient of \(K\) is \(4\).

Step2: Recall the relationship between coefficient and number of molecules

In a chemical equation, the coefficient represents the number of moles or molecules (in the context of the question asking for molecules) of the substance.

Answer:

\(4\)
