and Balance the following the chemical equation
Blank Mg + Blank O2 → Blank MgO
To balance the chemical equation:
Mg + O2 → MgO
We need to make sure that there is an equal number of each type of atom on both sides of the equation.
To balance the number of atoms for magnesium (Mg), we can put a coefficient of 2 in front of "Mg" on the left-hand side of the equation:
2Mg + O2 → MgO
Now, we need to balance the number of atoms for oxygen (O). On the right-hand side, there are already two oxygens from the magnesium oxide (MgO). Therefore, we need to balance the oxygen atoms on the left-hand side by putting a coefficient of 2 in front of "O2":
2Mg + 2O2 → MgO
The balanced chemical equation is:
2Mg + 2O2 → 2MgO
To balance the chemical equation: Blank Mg + Blank O2 → Blank MgO, we need to ensure that the number of atoms on both sides of the equation is the same.
Let's start by balancing the magnesium (Mg) atoms. We have one Mg atom on the left side and one Mg atom on the right side, so they are already balanced.
Next, let's balance the oxygen (O) atoms. On the left side, we have one O2 molecule, which means we have two O atoms. On the right side, we have one MgO molecule, which means we have one O atom.
To balance the oxygen atoms, we need to add a coefficient in front of MgO. Since we only have one O atom on the right side, we need to put a 2 coefficient in front of MgO to balance the equation:
Mg + O2 → 2MgO
Now the equation is balanced with one magnesium atom and two oxygen atoms on both sides.
To balance the chemical equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's go step by step:
1. Begin with the unbalanced equation:
Blank Mg + Blank O2 → Blank MgO
2. Count the number of atoms of each element on each side of the equation.
Left side: 1 Mg atom, 0 O atoms
Right side: 1 Mg atom, 1 O atom
3. Start by balancing the atoms that appear in only one compound. In this case, it's magnesium (Mg). To balance Mg, we need to have an equal number of Mg atoms on both sides of the equation.
Blank Mg + Blank O2 → Blank MgO
Since there is one Mg atom on both sides, we can proceed to balancing the oxygen (O) atoms.
4. On the right side, there is 1 O atom from MgO. Therefore, we need to balance it by putting a coefficient in front of O2 on the left side.
Blank Mg + Blank O2 → Blank MgO
Now, we have:
1 Mg(atom) + Blank O2 → 1 MgO(molecule with 1 Mg atom and 1 O atom)
5. Since O2 is a diatomic molecule (composed of two oxygen atoms), the coefficient in front of O2 should be 2 in order to balance the oxygen atoms.
Blank Mg + Blank O2 → Blank MgO
Now, we have:
1 Mg(atom) + 2 O2(molecules with 4 O atoms) → 1 MgO(molecule with 1 Mg atom and 1 O atom)
6. Review the entire equation to check if all the atoms are balanced:
Left side: 1 Mg atom, 4 O atoms
Right side: 1 Mg atom, 1 O atom
As we can see, the oxygen atoms are still not balanced. We need to make the coefficients of MgO equal to the number of Mg atoms (which is 1).
2 Mg + 2 O2 → 2 MgO
7. Final check:
Left side: 2 Mg atoms, 4 O atoms
Right side: 2 Mg atoms, 2 O atoms
Now, all the atoms are balanced, and the final balanced equation is:
2 Mg + 2 O2 → 2 MgO
