For questions #14 – 16, write an equation for the reaction of magnesium oxide with sodium chloride to produce magnesium chloride and sodium oxide.
14. Show the formulas of the reactants.
15. Show the formulas of the products.
16. Write the balanced the equation for this reaction
I have news for you. MgO and NaCl won't react as solids and they won't react in solution. However, I can write and balance the equation for you.
MgO + 2NaCl ==> MgCl2 + Na2O.
Aqueous reactions go to completion for one of three reasons.
1. A gas is formed.
2. A ppt is formed
3. A slightly ionized substance is formed.
The products are not gases, they are soluble and they are strong electrolytes.
To answer questions 14 to 16, we need to understand the chemical formulas of the reactants and products involved in the reaction between magnesium oxide and sodium chloride.
14. Show the formulas of the reactants:
Magnesium oxide is represented by the chemical formula MgO.
Sodium chloride is represented by the chemical formula NaCl.
15. Show the formulas of the products:
The reaction between magnesium oxide and sodium chloride yields magnesium chloride and sodium oxide.
Magnesium chloride is represented by the chemical formula MgCl2.
Sodium oxide is represented by the chemical formula Na2O.
Now, we can proceed to question 16, where we need to write the balanced equation for this reaction:
The unbalanced equation is:
MgO + NaCl → MgCl2 + Na2O
To balance this equation, we need to ensure there are equal numbers of atoms on each side.
First, let's balance the magnesium (Mg) atoms:
Since there is one Mg atom on the left side and one on the right side, the Mg atoms are already balanced.
Next, let's balance the chlorine (Cl) atoms:
There is one Cl atom on the left side, but two on the right side. We can balance the Cl atoms by placing a coefficient of 2 in front of NaCl on the left side, like this:
MgO + 2NaCl → MgCl2 + Na2O
Finally, let's balance the sodium (Na) and oxygen (O) atoms:
There are two Na atoms on the right side, but only one on the left side. We can balance the Na atoms by placing a coefficient of 2 in front of Na2O on the left side, like this:
MgO + 2NaCl → MgCl2 + 2Na2O
Now, all the atoms are balanced on both sides of the equation:
1 Mg atom, 2 O atoms, 2 Na atoms, and 2 Cl atoms on each side.
Therefore, the balanced equation for the reaction between magnesium oxide and sodium chloride is:
MgO + 2NaCl → MgCl2 + 2Na2O
