In water molecules from ice cores, the ratios of isotopes, 2H/¹H and 180/¹60 depends upon temperature of the water that precipitates from an air mass, and thus on average climatic temperatures. This allows climatologists to determine historical temperatures from analysis of the isotope ratios of hydrogen and oxygen in water molecules from ice cores. As temperature increases, the 180/160 ratio [Select] and the 2H/¹H ratio [Select]

4. The “alum” used in cooking is potassium aluminum sulfate hydrate, KAl(SO4)2 ∙ x H2O. To find the value of x, you can heat a sample of the compound to drive off all of the water and leave only KAl(SO4)2.Assume you heat 4.74 g of the hydrated compound and that the sample loses 2.16 g of water. What is the value of x?
Potentially Useful Information Spectrochemical Series: I < Br < SCN° < Cl° < NO3¯ < F < OH° < C2O4²-~ H2O < NCS < NH3 < en < PPH3 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 the same rules that we used for Cu(II), Ni(II), and Co(II). The Jahn-Teller Effect does not apply. Complete each statement or answer each question below about the solutions in the three test tubes.
