- Give the chemical name of the following: FeCl2 H2S Hg2Br2 NH4l Fe4[Fe(CN)6]3arrow_forward19. Which of the following species are isoelectric with each other? C, Cl–, Mn+2, B–, Ar, Zn, Fe+3, Ge+2.arrow_forwardTwo different compounds have the formulation CoBr(SO4)·5NH3. Compound A is dark violet, and compound B is red-violet. When compound A is treated withAgNO3(aq), no reaction occurs, whereas compound B reacts with AgNO3(aq) to form a white precipitate. When compound A is treated with BaCl2(aq), a white precipitate is formed, whereas compound B has no reaction with BaCl2(aq). Answer the following questions: a. Is Co in the same oxidation state in these complexes? Explain the reactivity of compounds A and B with AgNO3(aq) and BaCl2(aq). b. Are compounds A and B isomers of one another? If so, which category from isomers best describes the isomerism observed for these complexes? c. Would compounds A and B be expected to be strong electrolytes, weak electrolytes, or nonelectrolytes?arrow_forward
- Mercury ions, Hg(1) and Hg(II), are poisonous due to their ability to displace other metal ions in enzymes and disrupt the biological function. a) Are these ions hard or soft? b) Common ligands for metal ions in biological environments are amino acids (building blocks of proteins). Of the amino acids depicted below (focus on the highlighted atoms), which would be the best ligand for Hg(1) and Hg(II), and why? H H H O H3Nt CH2 H H H3N* -c CH2 H3Nt C-c CH2 H3Nt CH2 H3N+-C-c CH CH2 HO CH3 OH SH он H2N H2N Serine (S) Ser Threonine (T) Thr Cysteine Сys Tyrosine (Y) Asparagine (N) Glutamine (Q) Asn Тyr Gln c) Other metal ions that are toxic at certain concentrations include cadmium, chromium, iron, arsenic, and lead. For each of these metals, predict whether they would have similar chemistry to mercury using HSAB concepts. (Note that toxicity is dose-dependent; even water can be poisonous at too high a concentration in the body)arrow_forwardWhat is the electron configuration of the cobalt ion in Co(NO3)3?
