Use vespr theory to predict the molecular shape of the following molecules.

4. carbon dioxide (co2)
5. methane (ch4)
6. the nitrate ion [no3]−

4. Carbon dioxide.

The steric number is 2 with no lone pairs so it is Linear.

5. Methane CH4  has steric number 4 and no lone pairs so its tetrahedral.

6.  Nitrate ion NO3] has steric number of 3 and no lone pairs so its trigonal planar,.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
