Answer:

Expow do revolutions occur? In Tunisia, the street vendor Mohamed Bouazizi set himself on fire after his produce cart was confiscated. The injustice of this event provided an emblem for the widespread conditions of poverty, oppression, and humiliation experienced by a majority of the population. In this case, the revolutionary action might be said to have originated in the way that Bouazizi’s act sparked a radicalization in people’s sense of citizenship and power: their internal feelings of individual dignity, rights, and freedom and their capacity to act on them. It was a moment in which, after living through decades of deplorable conditions, people suddenly felt their own power and their own capacity to act. Sociology is interested in studying the conditions of such examples of citizenship and powerlanation:

what would the total pressure of a mixture of fluorine, chlorine, and bromine gases be if the partial pressure are 2.20 atm, 6.7

astraxan [27]

Answer:

The total pressure would be 8, 93 atm

Explanation:

We apply Dalton's laws, where for a gaseous mixture, the total pressure (Pt) is the sum of the partial pressures (Px) of the gases that make up the mixture.

Pt= Pxa + Pxb+ Pxc....

Pt=2, 20 atm+ 6, 70 atm+ 0,03 atm= 8, 93 atm

25 g of a compound is added to 500 mL of water if the freezing point of the resulting solution is

vlabodo [156]

Answer:

a) 119 g/mol

Explanation:

-We apply the formula for freezing point depression to obtain the molality of the solution:

$\bigtriangleup T_f=K_fm, \ \ K_f=1.36\textdegree C/m\\\\\therefore m=\frac{\bigtriangleup T_f}{K_f}\\\\=\frac{0.57\textdegree C}{1.36\textdegree C}\\\\=0.4191\ mol/Kg\\\\$

#We use the molality above to calculate the molar mass:

$m=\frac{0.4191\ mol}{1\ Kg}=\frac{25\ g}{0.5\ Kg}\\\\\therefore 1 \ mol=\frac{25\ g}{0.5\ Kg}\times\frac{1\ Kg}{ 0.4191}\\\\=119.3033\approx 119\ g/mol$

Hence, the molar mass of the compound is 119 g/mol
