- 3.118 Consider common sugars such as glucose (C6H12O6) and sucrose (C12H22O11). What type of chemical bonding would you expect to find in these chemicals?arrow_forwardConsider the following data for three binary compounds of hydrogen and nitrogen: %H (by Mass) %N (by Mass) I 17.75 82.25 II 12.58 87.42 III 2.34 97.66 When 1.00 L of each gaseous compound is decomposed to its elements, the following volumes of H2(g) and N2(g) are obtained: H2(L) N2(L) I 1.50 0.50 II 2.00 1.00 III 0.50 1.50 Use these data to determine the molecular formulas of compounds I, II, and III and to determine the relative values for the atomic masses of hydrogen and nitrogen.arrow_forwardGallium arsenide, GaAs, has gained widespread use in semiconductor devices that convert light and electrical signals in fiber-optic communications systems. Gallium consists of 60.% 69Ga and 40.% 71Ga. Arsenic has only one naturally occurring isotope, 75As. Gallium arsenide is a polymeric material, but its mass spectrum shows fragments with the formulas GaAs and Ga2As2. What would the distribution of peaks look like for these two fragments?arrow_forward
- A platinum-containing compound, known as Magnuss green salt, has the formula [Pt(NH3)4][PtCl4] (in which both platinum ions are Pt2+). Name the cation and the anion.arrow_forwardSodium ions, Na+, form ionic compounds with fluoride ions, F, and iodide ions, I. The radii of these ions are as follows: Na+ = 116 pm; F = 119 pm; and l = 206 pm. In which ionic compound, NaF or Nal, are the forces of attraction between cation and anion stronger? Explain your answer.arrow_forwardClassify the following compounds as electrolytes or nonelectrolytes. (a) potassium chloride, KCL (b) hydrogen peroxide, H2O2 (c) methane, CH4 (d) barium nitrate, Ba(NO3)2arrow_forward
