the balanced equation for magnesium chlorate = magnesium chloride + oxygen
6H^+ 6e + ClO3^- ==> Cl^-+ 3H2O is the half equation for chlorate but since Mg(ClO3)2 requires two chlorate so multiply by 2 and add Mg^2+.
12H^+ + 12e + Mg(ClO3)2 ==> MgCl2 + 6H2O
To write a balanced equation for the reaction between magnesium chlorate and magnesium chloride, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's how you can do it:
1. Begin by writing the chemical formula for magnesium chlorate, which is Mg(ClO3)2. This tells us that each molecule of magnesium chlorate contains one magnesium (Mg) atom, two chlorate (ClO3) ions, and a total of six oxygen (O) atoms.
2. Next, write the chemical formula for magnesium chloride, which is MgCl2. This shows us that each molecule of magnesium chloride contains one magnesium atom and two chloride ions.
3. Now, we can write the unbalanced equation:
Mg(ClO3)2 → MgCl2 + O2
4. To balance the equation, start by balancing the elements other than oxygen and chlorine. In this case, we only have magnesium, which is already balanced on both sides.
5. Next, balance the chlorine atoms by adding a coefficient of 3 in front of MgCl2, making it 3MgCl2. This way, we have 6 chlorines on both sides of the equation.
6. Now, let's balance the oxygen atoms. We have 6 oxygen atoms on the left side (2 from each ClO3) and only 2 oxygen atoms on the right side from the O2 molecule. To equalize the number of oxygen atoms, add a coefficient of 3 in front of O2, giving us 3O2.
Finally, the balanced equation for the reaction between magnesium chlorate and magnesium chloride is:
2Mg(ClO3)2 → 3MgCl2 + 3O2
