1. What are the values for the pH, POH, [H*], and [OH-] for a solution made by mixing 10 mL of 1.5 HCl (a strong acid) with 10 ml of 1.2 M NaOH (a strong base)? (Hint: Determine the volume for the equivalence point first and then figure out if you are before or after the equivalence point)

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
