SOLVE STEP BY STEP IN DIGITAL FORMAT Structure of Metal Materials: 8. A colleague calculated the density of iron with BCC structure using the following data of atomic radius equal to 1.24 Angstrom and atomic weight of 55.85 as follows: p = [(4 atoms/C. U.) x (55.85 g/atomic weight) / (atoms/atomic weight) / [2(1.24x108 cm)/√2]³ p = 68.8 g/cm³

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. The coordination complex causing the orange solution causes a larger splitting between the d orbitals of the metal then the coordination complex causing the... O red solution. O yellow solution. What color light does the…

A student is given an unknown metal “M” which reacts with iron and copper, but not with magnesium. Where would you position “M” in the reactivity series? Explain.
