How do ionic compounds and molecular compounds behave differently in solution?

Lelu [443]

Answer : Molecular compounds dissolve in water by means of dipole-dipole attractions and hydrogen bond attractions. These attractions between the molecular compound and water don't form ions when a molecular compound dissolves.

Explanation: I hoped that helped,

identify the postulate of Dalton's theory that is violated by the following observations: 59.95% of one sample of titanium dioxi

Inga [223]

Answer: This violates the law of constant composition.

Explanation:

Dalton's theory is based on mainly two laws, which are law of conservation of mass and law of constant composition.

Law of constant composition states that a compound always contain the elements in the fixed ratio by their masses.

For Example: In water $(H_2O)$ , the hydrogen and oxygen are present in the fixed ratio of 1 : 9 by their mass.

We are given:

A sample of titanium dioxide having 59.95 % of titanium and another sample of titanium dioxide having 60.10 % of titanium.

As, the compound is titanium dioxide. So, the mass percent of titanium must remain the same in both the elements.

Hence, this violates the law of constant composition.

The decomposition of N I 3 to form N 2 and I 2 releases − 290.0 kJ of energy. The reaction can be represented as 2N I 3 (s)→ N 2

ella [17]

Answer:

The change in enthaply when 10.0 g of nitrogen triiodide decomposes is -3.67 kJ.

Explanation:

$2NI_3 (s)\rightarrow N_2 (g)+3 I_2 (g), \Delta H_{rxn} =-290.0 kJ$

Enthalpy of the reaction when 2 moles of nitrogen triiodide decomposed = $\Delta H_{rxn}$

$\Delta H_{rxn} = -290.0 kJ$

Enthalpy of the reaction when 1 moles of nitrogen triiodide decomposed :

$\Delta H=\frac{\Delta H_{rxn}}{2}=\frac{-290.0 kJ}{2} =-145.0 kJ$

Mass of nitrogen triiodide decomposed = 10.0 g

Moles of nitrogen triiodide = $\frac{10.0 g}{395 g/mol}=0.02532 mol$

Change in enthaply when 0.02532 moles of nitrogen triiodide decomposed:

$\Delta H\times 0.02532=-145 kJ\times 0.02532=-3.67 kJ$
