Option 1
1.Draw up schemes for the formation of bonds between the atoms of the following elements:
C and AI; N and P ; N and O .
2. What kind of bond and type of crystal lattice do the following compounds have:
CuO, Hg, P2O5, P, CaCl2..
Assume their physical properties.
3. Specify which process is depicted by the following scheme (oxidation or reduction) and make an electronic balance corresponding to this scheme:
a) Na0 →Na+1 b) P0→P+5 c) AI+3 → AI0
4. Make up the redox reactions and arrange the coefficients by the electronic balance method:
a) H2O + F2 → HF + O2
b) SO2 +H2 → H2S +H2O
c) H2SO4 + C → SO2+CO2+H2O
