1. The problem is to balance the chemical equation: \[ \text{MgCo}^{5+} + 2\text{HC1} = \text{Mg} 1^{2} + \text{CO}^{2} + \text{H}^{2}\text{O} \]. 2. First, identify the correct chemical formulas and species involved. It seems the equation is intended to represent a reaction involving magnesium (Mg), cobalt ion (Co), hydrochloric acid (HCl), carbon dioxide (CO2), and water (H2O). 3. The correct balanced chemical equation should be: $$ \text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2 $$ or if cobalt is involved, clarify the species and charges. 4. Since the given equation is unclear and contains notation errors (e.g., MgCo⁵+2HC1, mg 1²), please provide the correct chemical species and their states. 5. Balancing chemical equations requires equal numbers of each atom on both sides. 6. For example, balancing \[ \text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2 \] involves: - 1 Mg atom on both sides - 2 H atoms on both sides - 2 Cl atoms on both sides 7. If you clarify the intended reaction, I can help balance it step-by-step.
