Calculate the concentration of each substance when mixing 40.0 mL of 0.1 M CH3COOH and 10.0 mL of 0.1 M CH3COONa?
Arrange the following reactions according to increasing change of entropy values. A. CH4(g) + H2O (g) = CO(g) + 3H2(g) B. C(s) + O2(g) = CO2 (g) C. H2O2(liquid) = H2O(liquid) + 1/2 O2 (g)
