<u>Gay lussas law:</u>
Gay-Lussac law states that the pressure for a given gas’ mass changes directly to an absolute gas temperature, provided that the volume held to be constant. The mathematical expressions of Gay-Lussac law also correspond to those of Charles Law:
This gas law is important because it shows that an increase in gas temperature increases the pressure proportionally (if the volume does not change). Similarly, as the temperature decreases, the pressure decreases proportionally.
Answer:
The enthalpy change for the solution process 
= - 158.34 kJ/mol
Explanation:
Given that:
The mass of salt AX = 2.499 g
The mass of water = 135.3 g
The mass of the solution = ( 2.499 + 135.3 ) g = 137.799 g
The specific heat of salt solution s is known to be = 4.18 J/g° C
The change in temperature i.e. ΔT = 35.2 °C - 23.6 °C = 11.6 °C
Thus, the amount of heat raised is equal to the heat absorbed by the calorimeter.
∴
Recall that the mass of the salt = 2.499 g
The number of moles of the salt = 
= 0.0422 mol of AX
Finally the enthalpy change, 
= - 158.34 kJ/mol
The enthalpy change for the solution process = - 158.34 kJ/mol
Answer:
The correct answer is option (3) "using nonviolent tactics such as boycotts and hunger strikes".
Explanation:
Cesar Chavez was a leader of American labor and civil right activists that fought to unionized migrant farm workers by the creation of The National Farm Workers Association. Cesar Chaves used nonviolent tactics to support the migrant farm workers. For instance, when Filipino American farm workers protested for higher wages in 1965, he encouraged Americans to boycott table grapes to support them; while he once performed a 24-day hunger strike in 1972 in the Santa Rita Center as a response to Arizona prohibiting boycotts and strikes by farm workers.
Anger, depression and suicidal thoughts
The answer is B, this is a synthesis reaction. A good way to identify a synthesis reaction is when there are multiple reactants, but only one product.
