Balance the following the chemical equation
Blank MgO + Blank CaS → Blank Mgs + Blank CaO
MgO + CaS → MgS + CaO
To balance the chemical equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation.
The unbalanced chemical equation is:
MgO + CaS → Mgs + CaO
Let's start by counting the number of atoms for each element on each side of the equation:
MgO: 1 Mg atom, 1 O atom
CaS: 1 Ca atom, 1 S atom
Mgs: 1 Mg atom, 1 S atom
CaO: 1 Ca atom, 1 O atom
To balance the equation, we need an equal number of each element on both sides.
Let's balance the atoms one by one:
1. Balancing magnesium (Mg):
We have 1 Mg atom on the left side and 1 Mg atom on the right side. The magnesium is already balanced.
2. Balancing oxygen (O):
We have 1 O atom on the left side and 1 O atom on the right side. The oxygen is already balanced.
3. Balancing calcium (Ca):
We have 1 Ca atom on the left side and 1 Ca atom on the right side. The calcium is already balanced.
4. Balancing sulfur (S):
We have 1 S atom on the left side and 1 S atom on the right side. The sulfur is already balanced.
The balanced chemical equation is:
MgO + CaS → MgS + CaO
To balance a chemical equation, follow these steps:
Step 1: Count the number of atoms of each element on both sides of the equation.
Blank MgO + Blank CaS → Blank Mgs + Blank CaO
On the left side:
- Magnesium (Mg): Blank MgO contains 1 Mg atom
- Oxygen (O): Blank MgO contains 1 O atom
- Calcium (Ca): Blank CaS contains 1 Ca atom
- Sulfur (S): Blank CaS contains 1 S atom
On the right side:
- Magnesium (Mg): Blank Mgs contains 1 Mg atom
- Oxygen (O): Blank CaO contains 1 O atom
- Calcium (Ca): Blank CaO contains 1 Ca atom
Step 2: Balance the elements one at a time by adding coefficients in front of the chemical formulas.
To balance Mg, you need to have the same number of Mg atoms on both sides. Since there is 1 Mg atom on each side, no coefficient is needed.
To balance O, you need to have the same number of O atoms on both sides. Since there is 1 O atom on each side, no coefficient is needed.
To balance Ca, you need to have the same number of Ca atoms on both sides. Since there is 1 Ca atom on each side, no coefficient is needed.
To balance S, you need to have the same number of S atoms on both sides. Since there is 1 S atom on the left side and none on the right side, you need to add a coefficient of 1 to CaS.
The balanced equation is:
Blank MgO + Blank CaS → Blank Mgs + 1 CaO
