Question

CHM 1045 Chapter 2 Homework Write formulas and systematic names for the following compounds. Use tables 2.4, 2.5, and 2.6. Do not use prefixes for ionic compounds. (2 pts) 1. ferrous sulfate ferric sulfate cuprous fluoride cupric fluoride 2. Write the systematic (Stock) and the older (common /Latin) nomenclature for the following compounds. Use tables 2.4, 2.5 and 2.6. (2 pts) CuCrO Co(MnO4) Review the chapter notes and describe what a hydrate is. Include the overall phase of the substance. Write the balanced chemical reaction equation for anhydrous iron (II) sulfate becoming a heptahydrate, where "hepta-" means 7. Include the subscripts, such as s, L, g, and aq, for physical phases of reactants and products. Name the product also. Refer to hydrates in the chapter notes as well as to examples 2.10 and 2.11 (on hydrates) and sections 2.9 and 2.10 (on reactions) in the text. (2 pts) 3.

Explanation / Answer

1.

ferrous sulfate   ------------ FeSO4 --------- Iron(II) sulfate

ferric sulfate ------------- ---- Fe2(SO4)3 ------ Iron(III) sulfate

cuprous fluoride-------------CuF-------------- Copper(I)fluoride

cuproic fluoride-------------- CuF2------------- copper(II)fluoride

2.

CuCrO4 ----------- Cupric chromate ----------- Copper(II) chromate

Co(MnO4)2 -------- Cobalt permanganate------------- CObalt(II) permanganate

3. FeSO4(s) + 7 H2O (l)--------------- FeSO4.7H2O(aq)

4.

Cl-S-S-Cl = S2Cl2 = Disulfur Dichloride

O=S=O = SO2= Sulfour DiOxide

PCl3 = Phosphorous trichloride

Br-I = Iodine Monobromide

5,.

Na2SO4---------- Sodium sulfate

(NH4)2S2O3---------------- Ammonium thiosulfate

NaHCO3 ---------------- Sodium Bicarbonate

                          = Sodium hydrogen carbonate
