Use the data provided to calculate benzaldehyde's heat of vaporization smartwork5
QveST [7]
This problem is incomplete. Luckily, I found a similar problem from another website shown in the attached picture. The data given can be made to use through the Clausius-Clapeyron equation:

ln(P₂/P₁) = (-ΔHvap/R)(1/T₂ - 1/T₁)

where
P₁ = 14 Torr * 101325 Pa/760 torr = 1866.51 Pa
T₁ = 345 K
P₂ = 567 Torr * 101325 Pa/760 torr = 75593.78 Pa
T₂ = 441 K

ln(75593.78 Pa/1866.51 Pa) = (-ΔHvap/8.314 J/mol·K)(1/441 K - 1/345 K)
Solving for ΔHvap,
<em>ΔHvap = 48769.82 Pa/mol or 48.77 kPa/mol</em>

Write the balanced NET ionic equation for the reaction when chromium(III) bromide and sodium phosphate are mixed in aqueous solu
Mariulka [41]

The balanced NET ionic equation for the reaction is CrBr₃(aq) + Na₃PO₄(aq) ==> CrPO₄(s) + 3NaBr(aq)

<h3>What is a balanced Ionic equation ?</h3>

In a balanced ionic equation, the number and type of atoms are the same on both sides of the reaction arrow.

Additionally, the net charge is the same on both sides of the equation.

Separate into the complete ionic equation.

It should be obvious that the aquous solutions ionize and the solid is shows as the molecule since it doesn't dissolve.

Cr³⁺(aq) + 3Br⁻(aq) + 3K⁺(aq) + PO₄³⁻(aq) ==> CrPO₄(s) + 3K⁺(aq) + 3Br⁻(aq)

Now look and cancel those ions common to both sides. What is left is the net ionic equation.

Cr³⁺(aq) + PO₄³⁻aq) ==> CrPO₄(s)
