"balance the following equation for a half reaction that occurs in basic solution. use e– as the symbol for an electron."
ago --> ag2o

H₂O + 2AgO + 2e⁻ → Ag₂O + 2OH⁻

Explanation:

AgO → Ag₂O

2AgO → Ag₂O

2AgO → Ag₂O + H₂O

2H⁺ + 2AgO → Ag₂O + H₂O

2H₂O + 2AgO → Ag₂O + H₂O + 2OH⁻, we cancel H₂O on both sides:

H₂O + 2AgO → Ag₂O + 2OH⁻

H₂O + 2AgO + 2e⁻ → Ag₂O + 2OH⁻

Now the equation is balanced, both sides have the same number of atoms and the same charge.
