12 is a solution of the equation 4x-5 = 3x+10

Show graphically that the system of equations 2x + 4y = 10 and 3x + 6y = 12 has no solution.

Ionisation constant of CH_(3)COOH is 1.7 xx 10^(-5) and concentration fo H^(+) in certain acetic acid solution is 3.4 xx 10^(-4) M . The concentration of acetic acid solution is

1 litre of 1M CH_(3)COOH (very weak acid) taken in a container initially. Now this solution is diluted upto volumen V (litre) so that pH of the resulting solution becomes twice the original value. (K_(a) (CH_(3)COOH) = 10^(-6)) . Now equal volume of 0.5 xx 10^(-6)M NaOH solution is added to this resulting solution, so that a buffer solution is obtained. Find pH of final solution (log 3 = 0.477 ).

A solution of glucose in water is labelled as 10 "percent" w//w , what would be the molality and mole fraction of each component in the solution? If the density of the solution is 1.2 g mL^(-1) , then what shall be the molarity of the solution?
