Identify the molecules in the beaker as weak acid (WA), strong acid (SA), weak base (WB), or strong base (SB), acidic salt (A salt), basic salt (B salt) or neutral salt (N salt). Determine the pH of the 3 circled molecules given a 1 L beaker containing 0.025 M solution of the given molecule. (C6H5CHCOOH, Ka

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
