11. 12) A potassium hydroxide (KOH) solution has a molar concentration of 0.026 M. Calculate the [H3O+], [OH-] and pH of the solution. Remember that Kw= 1.0 x 10-14M2 o TH0+1= 3.8x10-13. TOH1=2.6x10-2M, pH=12.42

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

According to the tide table below what time of day will the highest tide occur?

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
