WebApr 8, 2024 · Step 5: Balance the charge of each equation with electrons. The chromium reaction has (14+) + (2-) = 12+ on the left side and (2 * 3+) = 6+ on the right side. To balance, add 6 electrons (each with a charge of -1) to the left side: 6e − + 14H + (aq) + Cr 2O2 − 7 (aq) → 2Cr3 + (aq) + 7H 2O(l) WebIt contains one proton and one electron; thus, its net charge is zero. If hydrogen loses its electron, it forms the cation \text {H}^+ H+ (left column). The \text {H}^+ H+ cation has a net charge of 1+ from the one proton in …
