Answer:
Ba²⁺(aq) + SO₄²⁻(aq) ⟶ BaSO₄(s)
Explanation:
There are three steps you must follow. You must write the:
- Molecular equation
- Ionic equation
- Net ionic equation
A. Molecular equation
BaCl₂(aq) + Na₂SO₄(aq) ⟶ BaSO₄(s) + 2NaCl(aq)
B. Ionic equation
You write all the soluble substances as ions.
Ba²⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + SO₄²⁻(aq) ⟶ BaSO₄(s) + 2Na⁺(aq) + 2Cl⁻(aq)
C. Net ionic equation
To get the net ionic equation, you cancel the ions that appear on each side of the ionic equation.
Ba²⁺(aq) + <u>2Cl⁻(aq) </u>+ <u>2Na⁺(aq</u>) + SO₄²⁻(aq) ⟶ BaSO₄(s) + <u>2Na⁺(aq)</u> + <u>2Cl⁻(aq)
</u>
The net ionic equation is
Ba²⁺(aq) + SO₄²⁻(aq) ⟶ BaSO₄(s)

Solids are compounds whose atomic bonds are rigid, which doesn't let the atoms move around freely
1.59moles
Explanation:
Mass of CaO = 89.23g
Unknown
Number of moles = ?
Solution:
The mole is a unit of measurement in chemistry used to delineate the number of particles an atom contains.
A mole of a substance contains the avogadro's number of particles.
Number of moles = 
Molar mass of CaO = 40 + 16 = 56g/mol
Number of moles = 
= 1.59moles
