Answer:
Mass = 6.79 g
Explanation:
Molarity = 0.155
Volume = 0.75L
Mass = ?
The relationship between these quantities is given as;
Molarity = Number of moles / Volume
Number of moles = Volume * Molarity
Number of moles = 0.75 * 0.155 = 0.11625 moles
Number of moles = Mass / Molar mass
Mass = Molar mass * Number of moles
Mass = 58.44277 g/mol * 0.11625 mol
Mass = 6.79 g
Answer:
Net ionic equation:
Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)
Explanation:
Chemical equation:
BaCl₂ + Na₂SO₄ → BaSO₄ + NaCl
Balanced Chemical equation:
BaCl₂(aq) + Na₂SO₄(aq) → BaSO₄(s) + 2NaCl(aq)
Ionic equation:
Ba²⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)+ 2Na⁺(aq) + 2Cl⁻ (aq)
Net ionic equation:
Ba²⁺(aq) + SO₄²⁻(aq) → BaSO₄(s)
The Cl⁻(aq) and Na⁺ (aq) are spectator ions that's why these are not written in net ionic equation. The BaSO₄ can not be splitted into ions because it is present in solid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
