5. Consider a case in which the solubilities of two substances (we will call them Substance A and an impurity Substance B) are both 1.000g/ 100.0 mL of solvent at 20.0 C and 10.000 g/100.0 ml of solvent at 100.0 °C (their solubilities are independent of each other, meaning that 1.000 g A and 1.000 g B can dissolve in 100.0 mL solvent at 20.0°C 10.000 g A AND 10.000 g B can dissolve in 100.0 mL solvent at 100.0*c)....

PART IV. MISCIBILITY OF TWO LIQUIDS
1. For the first two liquids in Table IV-B (the solvents in the
miscibility tests), use the molecular structures provided in the
Introduction to identify each liquid as polar or nonpolar. Put an X
in the appropriate column.
2. For the remaining liquids in Table IV-B, determine if they
are primarily polar, primarily nonpolar, or both polar and polar
based on your observations in Table III-A and based on the polarity
of the solvent....

Question 5 6 pts A student has three test tubes containing a metal (M) nitrate solution M(NO3)2 (aq) (where "M" represents a generic transition metal). The student adds aqueous ammonia (NH3) to one test tube, aqueous hydrochloric acid (HCI) to the second tube, and nothing more to the third tube, but forgets to label the tubes. After this, one test tube contains a red solution, one an orange solution, and one a yellow solution. Note: This metal, M, would follow...

Which of the following best describes London dispersion forces. Question 1 options: the intermolecular forces that exist when ions from an ionic compound are attracted to the dipole of polar molecules in a mixture. involves molecular orientations in which the positive end of one dipole is near the negative end of another forces that exist only between molecules that contain hydrogen atoms bonded to highly electronegative atoms such as O, N, F. Interactions between temporary dipoles cause atoms to be...
