The kp for the reaction below is 1.49 × 108 at 100.0°c:

co(g) + cl2(g) → cocl2(g)

in an equilibrium mixture of the three gases, pco = pcl2 = 2.22 × 10-4 atm. the partial pressure of the product, phosgene (cocl2), is atm.

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.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
