Answer 1

To balance the chemical equation:

\[ \underline{MgO} + \underline{CaS} \rightarrow \underline{MgS} + \underline{CaO} \]

we'll follow these steps:

1. Identify the number of each type of atom in the reactants and products:

   • Reactants:
     • Mg: 1 (from MgO)
     • O: 1 (from MgO)
     • Ca: 1 (from CaS)
     • S: 1 (from CaS)
   • Products:
     • Mg: 1 (from MgS)
     • S: 1 (from MgS)
     • Ca: 1 (from CaO)
     • O: 1 (from CaO)

2. Write the unbalanced equation: \[ \text{MgO} + \text{CaS} \rightarrow \text{MgS} + \text{CaO} \]

3. Set up the balanced coefficients: Since there is one of each element on both sides, the equation is already balanced.

Thus, the coefficients are:

• Blank 1: 1
• Blank 2: 1
• Blank 3: 1
• Blank 4: 1

So the balanced equation is: \[ 1 \text{ MgO} + 1 \text{ CaS} \rightarrow 1 \text{ MgS} + 1 \text{ CaO} \]

Final values:

• Blank 1: 1
• Blank 2: 1
• Blank 3: 1
• Blank 4: 1
