Balance the following the chemical equation
Blank MgO + Blank CaS → Blank Mgs + Blank CaO
2MgO + CaS → MgS + CaO
To balance the chemical equation:
Blank MgO + Blank CaS → Blank MgS + Blank CaO
Step 1: Count the number of atoms for each element on both sides 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: 1
Step 2: Balance the metals first. In this case, balance the magnesium (Mg) and calcium (Ca).
Blank MgO + Blank CaS → Blank MgS + 1 CaO
Step 3: Balance the nonmetals. In this case, balance the oxygen (O) and sulfur (S).
Blank MgO + Blank CaS → Blank MgS + 1 CaO
Step 4: Double check the balance for all atoms.
On the left side:
1 Mg
1 O
0 Ca
1 S
On the right side:
1 Mg
1 O
1 Ca
1 S
Both sides of the equation are now balanced with the following equation:
MgO + CaS → MgS + CaO
To balance a chemical equation, we need to make sure that the same number of atoms of each element is present on both sides of the equation.
Let's start by counting the number of atoms on each side of the equation:
On the left side (reactants):
- Magnesium (Mg): Blank Mg
- Oxygen (O): Blank O
- Calcium (Ca): Blank Ca
- Sulfur (S): Blank S
On the right side (products):
- Magnesium (Mg): Blank Mg
- Oxygen (O): Blank O
- Calcium (Ca): Blank Ca
- Sulfur (S): Blank S
Since we want the equation to be balanced, we need the same number of each type of atom on both sides of the equation.
Let's balance the equation step by step:
1. Start with balancing the metals. In this case, we have magnesium (Mg) and calcium (Ca). Since there is only one Mg on the left side, we need only one Mg on the right side. Similarly, we only have one Ca on the right side, so we need only one Ca on the left side.
Blank MgO + Blank CaS → Blank MgS + Blank CaO
2. Next, let's balance the non-metal elements: oxygen (O) and sulfur (S). We have one O on the left side and one O on the right side, so they are already balanced. Similarly, there is one S on each side, so they are already balanced as well.
Blank MgO + Blank CaS → Blank MgS + Blank CaO
Therefore, the balanced chemical equation is:
MgO + CaS → MgS + CaO
