An aqueous solution contains dissolved C6H5NH3Cl and C6H5NH2. The concentration of C6H5NH2 is 0.60 M and pH is 4.29. Answer with the correct number of significant figures. (a) Calculate the concentration of C6H5NH3+ in this buffer solution.
(b) Calculate the pH after 3.9 g of NaOH(s) is added to 1.0 L of this solution. (Neglect any volume change.)

Yeah, but what are you trying to ask?

Try adding 700% because of the x in y

Reaction involved in present system is :   c12h22o11 + h2o → 2 c6h12o6the reaction system is obeying following rate law:   rate = k[c12h22o11]thus, it is a first order reaction.now, for 1st order reactionrate constant (k) =  given: initial conc. = 3.0 g, final conc. = 2.7 g, t = 2.5 h∴rate constant (k) =  ∴ k = 0.04215 h-1now, for 1st order reaction, half life = 0.693/k = 0.693/0.04215 = 16.4 hthus correct answer is option b

No, because shearing causes strike-slip faults and normal faults are caused by tension.
