The value of kb of cyclohexane in the given question is; kb = 2.82 °C/m
<h3>Understanding Molality of a Solution</h3>
Molality of solution = (Number of moles of C₆H₄Cl₂)/(Mass of Cyclohexane)
Now;
Number of moles of C₆H₄Cl₂ = Mass/molar mass = 2g/147 g/mol
Number of moles of C₆H₄Cl₂ = 0.0136 mol
Molality of solution = 0.0136/(22.5 * 10⁻³ kg)
Molality of solution = 0.6 m
Now, to find kb for cyclohexane, we will use the formula;
T_b(solution) - T_b(solvent) = kb × molality of solution
Thus;
82.39 - 70 = kb * 0.6
kb = (82.39 - 70)/0.6
kb = 2.82 °C/m

The workers were motivated to organize the pullman strike because the company cut their wages.
Pullman strike was resultant of reducing in compensation and terminating workers in response to a preferred currency collapse. An average pay cut was 33 percent. But on occasion, it increases to between 40% and 50%. The workforce's wage had already been reduced without the subsequent rent discounts.
The fact that the employee compensation was cut while the rent remained the same was the main reason for the Pullman strike. Beginning on May 11 of the same year, 1894, it was virtually an all-out railroad strike in the United States. As a gesture of goodwill toward the American labor movement in the midst of the crisis, President Grover Cleveland and Congress established Labor Day as a public holiday on June 28.

Chickens, chickens are a main source of protein both when you eat them and from their eggs they lay.
By Newton's second law, the net force on the object is
∑ F = 10.0 N + F = (7.0 kg) (1.0 m/s²)
where F is the unknown force. Since the object is accelerating to the east, F must be acting in the same or opposite direction as the known force that is also directed eastward. Solve for F :
10.0 N + F = 7.0 N
⇒ F = - 3.0 N
which is to say, F has magnitude 3.0 N and points toward the west.
