SOLVING EQUATIONSThe first equation below is balanced. However, the second equation is not balanced. What is missing from the right side of the second equation to make it true?Answer:The missing part is

Determine which of the following equations is not balanced correctly. Mg(s) + 2H2O(l) → Mg(OH)2(aq) + H2(g)N2(g) + 3H2(g) ⇌ 2NH3(g) C6H12O6(s) + 6O2(g) → 6CO2(g) + 6H2O(l) Fe2O3(s) + 2C(s) → 3Fe(s) + 2CO2(g)

Sally was given the following equation to balance: H2O → H2 + O2. She balanced it as follows: 2 HO → H2 + O2. What did she do wrong? What is the correct way to balance the equation?
