use the following balanced equation to answer the questions: 4k + o₂ → 2k₂o how many molecules of potassium are present?
Answer
Explanation:
Step1: Analyze the coefficient
In the balanced equation $4K + O_2\rightarrow2K_2O$, the coefficient of $K$ is 4.
Step2: Determine the number of molecules
The coefficient represents the number of moles of the substance. In terms of molecules, 1 mole of any substance contains Avogadro's number ($N_A = 6.022\times 10^{23}$) of particles. Here, since the coefficient of $K$ is 4, it means there are 4 atoms of potassium. Potassium is a mon - atomic element, so the number of potassium molecules is 4 (as potassium exists as individual atoms in this context).
Answer:
4
