- Failure of the Black Consciousness philosophy

- policy of integration (joining the privileged)

- politics of Elitism (replacing the privileged)


1. What is the molar concentration of Aki’s disinfectant if she dissolved 5Tbsp. of



NaClO (sodium hypochlorite) in 3.8 liters of H2O (water)?



2. Compute for the molality of her disinfectant if she dissolved 5Tbsp. of NaClO



(sodium hypochlorite) in 3.8 liters of H2O (water).



3. Calculate the percent by mass of sodium hypochorite in her disinfectant solution. (



5Tbsp. of NaClO (sodium hypochlorite) and 3.8 liters of H2O (water). In units of grams



for both of the solute and solvent.



4. Calculate the mole fraction of sodium hypochorite and water in Aki’s solution. (



5Tbsp. of NaClO (sodium hypochlorite) and 3.8 liters of H2O (water).



5. Calculate the percent by volume of the disinfectant Aki made. Units in mL.



6. What is the concentration of her solution in parts per million? ( 5Tbsp. of NaClO



(sodium hypochlorite) and 3.8 liters of H2O (water).

Modify the program from number 1 by adding a class and apply the "outside of a class function".

when stored in containers made of sodium silicate, hydrofluoric acid attacks the container to give hexafluorosilicic acid, sodium fluoride and water. write and balance the reaction between sodium silicate and hydrofluoric acid. how many grams of hydrofluoric acid is needed to completely dissolve a 100.0-gram weighing beaker made of sodium silicate?

multiple rivers that are carrying water from melting snow from many mountains to feed Van Lake during springtime. these mountains get around 1.96 km^3 snowfall through winter. if all the snow melts at once, calculate the change in the water level of Van Lake in meters? ( Van Lake surface area: 3713 km^2 , d(snow) = 0.92 g/cm^3 , d(water) = 1.0 g/cm^3 )

Let X and Y be two independent, nonnegative integer-valued random variables whose distribution has the property



P( X=x|X+Y=x+y)= binom m x binom n y binom m+n x+y



for all nonnegative integers x and y where m and n are given positive integers. Assume that P(X = 0) and P(Y = 0) are strictly positive. Show that both X and Y have binomial distributions with the same parameter p, the other parameters being m and n respectively.

1.Convert the 1-D array to 3-D array


a = np.array([x for x in range(32)])



Answer:



print(o)



Output:


array([[[ 0, 1, 2, 3, 4, 5, 6, 7],


[ 8, 9, 10, 11, 12, 13, 14, 15]],



[[16, 17, 18, 19, 20, 21, 22, 23],


[24, 25, 26, 27, 28, 29, 30, 31]]])



2.Convert the value in the array to appropriate data type


a = np.array([[7.2, 5.4, 9.3],


[3.8, 6.7, 8.5]])



Answer:



print(o)



Output:


[[7 5 9]


[3 6 8]]



3.Extract value in between 7 to 15 from the given array


a = np.array([2, 6, 1, 9, 10, 3, 27])



Answer:



print(o)



Output:


[ 8 12 9 11]
