The answer is
You must make sure each reactant has the same amount of subscripts on both sides of the equation.
Answer:
36 mol H
Explanation:
1 molecule C₆H₁₂O₆ contains 12 H atoms
1 mol C₆H₁₂O₆ contains 12 mol H atoms; Multiply by 3
3 mol C₆H₁₂O₆ contains 36 mol H atoms
If you are talking about moles of hydrogen molecules (H₂), you divide 36 by 2 and get 18 mol H₂.
Answer:
So, sodium oxide + water = sodium hydroxide + hydrogen is written Na2O+H2O-->NaOH+H.
To balance the equation it should read NaO+H2O-->2NaOH
Explanation:
Na2O+H2O-->2NaOH+0H2.......the 0H2 is dropped because there is no value
