Find the equation of the tangent line to the curve g(X)= 2cos(2X)/(3X) at the point x= pi/3

for the reaction system H2 + X2 <->2HX Kc = 24.4 at 300 K a system made up fron these components which is at equilibrium contains 0.150 moles of H2 and 0.600 moles of HX in a 3.00 liter. calculate the number of moles of X2 present at equilibrium.

If the OH ion concentration in an aqueous solution at 25 celsius is 3.4x10^-3 M the the H concentration in moles per liter in the same solution is? answers is 2.9x10^-12 i do the -log and i get 2.46 i don't know that else

At 60 celsius the value of Kw is 9.5x10^-14. considering this waht is the calculated value for the pOH of a 2.00x10^-3 M HCL solution at this temperature? the answer is 10.32 i do the -log and i get 11.31 please advice
