Question

use the following balanced equation to answer the questions:
2h₂ + o₂ → 2h₂o
how many molecules of hydrogen are present?

Explanation:

Step1: Analyze the coefficient in the chemical equation

In the balanced chemical equation \(2H_2 + O_2
ightarrow2H_2O\), the coefficient of \(H_2\) (hydrogen gas) is \(2\). In the context of chemical equations, the coefficient represents the number of molecules (or moles in a more general stoichiometric sense).

Answer:

\(2\)
