(Solved): Indicate with a + or a - which atom is more electropositive and which is more electronegative. ...

Indicate with a $$?+$$ or a $$?$$ - which atom is more electropositive and which is more electronegative. Then, using Linus Pauling's numbers, subtract their electronegativities from each other to calculate the nolaritv of the bond and declare it polar or nonpolar. Follow tha 1) $${?}_{1}C?\dots +H_1^H$$ 2). $$\frac{\mathrm{C}}{\mathrm{C}}?\mathrm{I}?\mathrm{N}$$ 3) $$\frac{C?1}{1}?\frac{0}{1}$$ 4) $$\frac{\mathrm{O}}{\mathrm{I}}?\mathrm{H}?$$ 5) N ...... H $$?{\mathrm{H}}_{?}=$$ 6) 7) $$\mathrm{Na}?\mathrm{Cl}$$ 8) $$\frac{1}{1}??\mathrm{N}$$
