Fill in the blanks and Balance the following the chemical equation
Blank Mg + Blank O2 → Blank MgO
Blank 1:
Blank 2:
Blank 3:
Blank 1: 2Mg
Blank 2: O2
Blank 3: 2MgO
The balanced equation is:
2Mg + O2 → 2MgO
Blank 1: 2Mg
Blank 2: O2
Blank 3: 2MgO
To balance a chemical equation, we need to make sure that there are the same number of atoms of each element on both sides of the equation.
In this case, we have the equation:
Mg + O2 → MgO
Let's start by counting the number of atoms for each element on both sides of the equation.
On the left side, we have:
1 Mg atom
2 O atoms (since O2 means there are 2 oxygen atoms)
On the right side, we have:
1 Mg atom
1 O atom
To balance the equation, we need to make sure that the number of atoms of each element is the same on both sides. Since we have 2 O atoms on the left side and only 1 O atom on the right side, we need to multiply the MgO on the right side by 2 to balance the equation:
Mg + O2 → 2 MgO
Now, let's check the number of atoms again:
On the left side, we still have:
1 Mg atom
2 O atoms
On the right side, we now have:
2 Mg atoms
2 O atoms
The equation is now balanced, with the same number of Mg and O atoms on both sides:
Mg + O2 → 2 MgO
