Fill in the blanks and Balance the following the chemical equation
Blank MgO + Blank CaS → Blank Mgs + Blank CaO
Blank MgO + Blank CaS → Blank MgS + Blank CaO
To balance the chemical equation:
MgO + CaS → MgS + CaO
To balance the equation, we must have the same number of each element on both sides of the equation.
1. Start by counting the number of atoms for each element:
On the left side:
Mg: 1
O: 1
Ca: 1
S: 1
On the right side:
Mg: 1
O: 1
Ca: 1
S: 1
2. Balance the elements one at a time. Begin with the elements that appear in the fewest compounds:
Let's balance the sulfur (S) atoms first:
MgO + CaS → MgS + CaO
Since there is only one sulfur (S) atom on each side of the equation, sulfur (S) is already balanced.
3. Now, balance the magnesium (Mg) atoms:
MgO + CaS → MgS + CaO
Since there is one magnesium (Mg) atom on the left side and one on the right side, magnesium (Mg) is already balanced.
4. Finally, balance the calcium (Ca) and oxygen (O) atoms:
MgO + CaS → MgS + CaO
To balance the calcium (Ca) atoms, we need to put a coefficient of 1 in front of CaS, and a coefficient of 1 in front of CaO:
MgO + 1CaS → MgS + 1CaO
To balance the oxygen (O) atoms, we need to put a coefficient of 1 in front of MgO and a coefficient of 1 in front of CaO:
1MgO + 1CaS → MgS + 1CaO
Therefore, the balanced chemical equation is:
MgO + CaS → MgS + CaO
To balance the chemical equation, we need to ensure that the number of atoms on both sides of the equation is equal.
The given equation is:
MgO + CaS -> Mgs + CaO
Let's count the number of atoms on each side of the equation:
On the left side:
Mg: 1
O: 1
Ca: 0
S: 1
On the right side:
Mg: 1
O: 1
Ca: 1
S: 0
From the counts, we can see that the number of Mg and O atoms are equal on both sides, but the number of Ca and S atoms are not equal.
To balance the equation:
MgO + CaS -> MgS + CaO
We need to place coefficients in front of the compounds.
The balanced equation is:
MgO + CaS -> MgS + CaO
This equation is balanced because it has the same number of atoms on both sides:
Mg: 1
O: 1
Ca: 1
S: 1
