Determine the ph of the solution at the points
A sample which is having 25.00 mL of 0.100 M CH3CO2H is titrated with the 0.100 M NaOH. Determine the pH of the solution at the points where the 24.5 and 25.5 mL of NaOH have been added. (Ka = 1.8 x 10-5)

Given the function f(x)= -3x^2 - 12x -4. Use axis of symmetry and y-intercept to determine the additional point on graph.
Determine the heat of decomposition for this process at constant pressure and 25°C. (Look up the standard enthalpy of formation of the reactant and products in the table:
Calculate the enthalpy of reaction per mole of CsOH? Suppose the densities of the solutions are all 1.00 g/mL and the specific heats of the solutions are 4.2 J/g*K.
The optic nerve requires a minimum of 2.0 * 10^-17 J of energy to trigger a series of impulses that eventually reach the brain. The human eye is a complex sensing device for the visible light.
Briefly describe how you could use the TLC to decide when the reaction was complete. Suppose you prepared benzhydrol by the reduction of benzophenone with the sodium borohydride.
The standard heat of reaction, for the reaction as written, is-114.1 kJ; it is exothermic. The reaction is 2 NO(g) +O2 (g) => 2 NO2 (g) Nitrogen monoxide reacts with the oxygen gas to give nitrogen dioxide.
