A DNA and chromosomes are found in different types of cells
Answer:
2H₂ + O₂ → 2H₂O.
Explanation:
- For the reaction of water formation:
<em>2H₂ + O₂ → 2H₂O.</em>
- It should apply the the law of conservation of mass that the no. of reactants atoms is equal to the no. of products atoms.
<em>So, every </em><em>2.0 moles of H₂ </em><em>react with </em><em>1.0 mole of O₂</em><em> to produce </em><em>2.0 moles of H₂O.</em>
