use the following balanced equation to answer the questions: 2h₂ + o₂ → 2h₂o how many molecules of hydrogen are present?
Answer
Explanation:
Step1: Identify coefficient of hydrogen
In the equation $2H_2 + O_2\rightarrow 2H_2O$, the coefficient of $H_2$ is 2.
Step2: Determine number of molecules
The coefficient represents the number of molecules in the balanced - chemical equation. So, there are 2 molecules of hydrogen.
Answer:
2
