Predict suppose four atoms of oxygen gas (02) and two atoms of hydrogen has (H2) are combined. determine how many atoms of water (H2O) and oxygen (O2) will be produced?

When four molecules of oxygen gas (O₂) and two molecules of hydrogen gas (H₂) are combined, they react to form water (H₂O). The balanced chemical equation for this reaction is 2 H₂ + O₂ → 2 H₂O. Thus, from the reaction of two molecules of H₂ with one molecule of O₂, two molecules of water (H₂O) will be produced, and one molecule of O₂ will remain unreacted.
