Question

use the following balanced equation to answer the questions: 4k + 2s → 2k₂s how many molecules of sulfur are present?

Explanation:

Step1: Identify coefficient of sulfur

In the balanced equation $4K + 2S
ightarrow2K_2S$, the coefficient of $S$ is 2.

Step2: Determine number of sulfur molecules

The coefficient represents the number of molecules in a balanced - chemical equation. So, there are 2 molecules of sulfur.

Answer:

2
