there is no oxygen in space for humans to breathe. so, astronauts living in space use electricity to break down water into hydrogen gas and oxygen gas. consider the following reaction: some amount of water (h₂o) reacts to produce 2 molecules of hydrogen (h₂) and 1 molecule of oxygen (o₂). use the number of atoms in the reaction to answer the question below. chemical element number of atoms in the reaction h 4 o 2 during this reaction, how many molecules of water (h₂o) react? submit work it out not feeling ready yet? this can help: describe the atomic composition of molecules (100)

Answer

Answer:

2

Explanation:

Step1: Analyze hydrogen atoms

Each $H_2O$ has 2 H - atoms. Total H - atoms are 4. So number of $H_2O$ for H - atoms is $\frac{4}{2}=2$.

Step2: Analyze oxygen atoms

Each $H_2O$ has 1 O - atom. Total O - atoms are 2. So number of $H_2O$ for O - atoms is $\frac{2}{1}=2$.
