4.En un laboratorio se necesita elaborar una disolución que tenga un punto de ebullición de 103 ºC. Para ello, se disponen 500 g de agua y de resorcina (C6H4(OH)2). ¿Qué cantidad de resorcina se requiere para elaborar la disolución? Considera que la Ke del agua es 0,52 ºC Kg/mol. Básate en las siguientes preguntas: a)¿Cuál es la variación de la temperatura de ebullición de la disolución y del agua? (2 ptos.)

b)¿Cómo calcularías la molalidad de la disolución a partir de la información? (3 ptos.)

c)Calcula la masa en gramos de resorcina que se debe utilizar para elaborar la solución requerida. (2 ptos.)

girl imma just put my comment here because i need a couple point okurrttt

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

you didnt put any of the following

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
