Which of the following should have the highest conductivity? a. 3.0 M NaCl b. 2.1 M Na3PO4 c. 2.4 M CaCl2 d. 3.2 M NH4NO3
Aleks [24]

Answer:

The correct answer is option b, that is, 2.1 M Na₃PO₄.

Explanation:

The solution with the largest concentration of ions will possess the highest conductivity.

a) 3.0 M NaCl

NaCl ⇔ Na⁺ + Cl⁻

Here the total number of ions is 2, therefore, the concentration of ions is 3.0 × 2 = 6.0 M

b) 2.1 M Na₃PO₄

Na₃PO₄ ⇔ 3 Na⁺ + PO₄³⁻

Here the total number of ions i 4. Therefore, the concentration of ions is

2.1 × 4 = 8.4 M.

c) 2.4 M CaCl₂

CaCl₂ ⇔ Ca²⁺ + 2Cl⁻

The total number of ions is 3. Therefore, the concentration of ions is

2.4 × 3 = 7.2 M

d) 3.2 M NH₄NO₃

NH₄NO₃ ⇔ NH₄⁺ + NO₃⁻

The total number of ions is 2. The concentration of ions will be,

3.2 × 2 = 6.4 M

Hence, the highest conductivity will be of 2.1 M Na₃PO₄.

<span>_____Balanced Chemical eqn___ C6H5OH + 7O2 --> 6C02 + 3H20 Firstly, heat of rxn will be absorbed by bobm calorimaeter, so find the qcal qcal = CΔT = (11.66 KJ/°C)(26.37°C- 21.36°C) = 58.42 KJ since the heat of rxn absorbed by calorimeter, assume: qrnx = -qcal = - 58.42 KJ _____q GRAM OF C6H5OH______ Find the number of moles you have by dividing the given grams of C6H5OH by its molar mass (1.8 g C6H5OH)(94 g/mole C6H5OH) = 0.0191 mol C6H5OH then divide qrnx by the number of moles. (-58.42 KJ)/(0.0191 mol C6H5OH) = -3058.64 KJ/mol C6H50H</span>
