En un laboratorio, un químico realiza una serie de separaciones del contenido de un frasco rotulado como X. El procedimiento es el siguiente: Se observa en el frasco X, un sólido sedimentado (Y), el contenido del frasco se filtra separando el sólido y al calentarlo, cambia de color y desprende un gas color café. El líquido obtenido de la filtración descrita al que llamaremos líquido (Z), al ser destilado produce dos líquidos de punto de ebullición diferente a los que llamaremos (B) y (C) respectivamente. Justifique que tipo de sustancia son Y, Z, y B según el análisis de la clasificación de la materia.

The pressure in a fluid is affected by which characteristics of that fluid

7. using your knowledge of colligative properties explain whether sodium chloride or calcium chloride would be a more effective substance to melt the ice on a slick sidewalk. use 3 – 4 sentences in your explanation. 8. when a 2.5 mol of sugar (c12h22o11) are added to a certain amount of water the boiling point is raised by 1 celsius degree. if 2.5 mol of aluminum nitrate is added to the same amount of water, by how much will the boiling point be changed? show all calculations leading to your answer or use 3 – 4 sentences to explain your answer. 9. if 5.40 kcal of heat is added to 1.00 kg of water at 100⁰c, how much steam at 100⁰c is produced? show all calculations leading to an answer. 10. the freezing of water at 0⁰c can be represented as follows: h2o (l) ↔ h2o(s) the density of liquid water is 1.00 g/cm3. the density of ice is 0.92 g/cm3. in 3 – 4 sentences explain why applying pressure causes ice to melt.
