When acids react with water, H ions are released which then combine with water molecules to form H₃O⁺
2H2O --> 2H2 + O2
The mole H2O:mole O2 ratio is 2:1
Now determine how many moles of O2 are in 50g: 50g × 1mol/32g = 1.56 moles O2
Since 1 mole of O2 was produced for every 2 moles of H2O, we need 2×O2moles = H2O moles
2×1.56 = 3.13 moles H2O
Finally, convert moles to grams for H2O:
3.13moles × 18g/mol = 56.28 g H2O
D) 56.28
Carbon Dioxide is formed when two oxygen atoms chemically combine with a carbon atom. The term that will best describe carbon dioxide is a compound. That will make the correct answer D.
Answer: because they take a lot of tie to form
