Question

1. answer the question regarding the following chemical reaction: 2h₂ + o₂ → 2h₂o. how many hydrogen atoms are needed to produce two 2h₂o?

Explanation:

Step1: Analyze the chemical equation

The given equation is $2H_2 + O_2
ightarrow2H_2O$. In water ($H_2O$), each molecule has 2 hydrogen atoms.

Step2: Determine hydrogen atoms for 2 $H_2O$

We want to produce 2 molecules of $H_2O$. Since each $H_2O$ has 2 hydrogen atoms, for 2 $H_2O$ molecules, the number of hydrogen atoms is $2\times2 = 4$.
