An 8.65-g sample of an unknown group 2a metal hydroxide is dissolved in 85.0 ml of water. an acid-base indicator is added and the resulting solution is titrated with 2.50 m hcl(aq) solution. the indicator changes color signaling that the equivalence point has been reached after 56.9 ml of the hydrochloric acid solution has been added.

[ad_1]

Answer;

The molar mass of metal hydroxide = 121.66 g/ mole

The formula is Sr(OH)2

Explanation;

M(OH)2 + 2 HCl = MCl2 + 2 H2O  

Moles of the acid = 2.5 x 56.9 / 1000 = 0.14225  

Therefore; moles of hydroxide at the eq point = 0.0711 moles  

These have a mass of 8.65g

Thus; mass of 1 mole = 8.65 / 0.0711

         = 121.66 g / mole  

That means the compound is Sr (OH)2 ..

Answer:

Henri Rousseau’s Portrait of a Woman

Explanation:

Magical Realism finds precedent in eighteenth-century Gothic novels, but also connects with sixteenth-century Baroque or Surrealism, almost contemporary in the early twentieth century.

Among the most striking features of this movement, we find the blend of realism with pure unreality that is observed as normal, with the integration of magical elements without seeming extraordinary.

These works do not explain the supernatural elements and are narrated as something natural, with characters unaware of their transcendent dimension. In addition, death has paramount value in the relativistic discourse of truth, with a metaphysical focus on space and time and an intimate atmosphere that blends characters with myths, legends, and natural cultures.

Henri Rousseau’s Portrait of a Woman is considered one of the first magical realistic stories.
