- When carbon dioxide dissolves in water it reacts to produce carbonic acid, H2CO3(aq), which can ionize in two steps. H2CO3(aq)HCO3(aq)+H+(aq)Kc1=4.2107HCO3(aq)CO32(aq)+H+(aq)Kc2=4.81011 Calculate the equilibrium constant for the reaction H2CO3(aq)CO32(aq)+2H+(aq)arrow_forwardActually, the carbon in CO2(g) is thermodynamically unstable with respect to the carbon in calcium carbonate(limestone). Verify this by determining the standardGibbs free energy change for the reaction of lime,CaO(s), with CO2(g) to make CaCO3(s).arrow_forwardit is determined through a titration experiment that the molarity of acetic acid, CH3COOH, in vinegar is 0.883 M. what is the %(w/v) of acetic acid in this vinegar sample?arrow_forward
- A brand of window-cleaning fluid is composed of ammonia solution, water, a colouring agent, and a very small quantity of soap. It has 0.15 mol/L concentration of NH3(aq). What is the pH of this fluid?arrow_forwardAdenosine triphosphate, ATP, is used to store energy within biological systems. It releases that energy by losing a terminal phosphate group, Pi, to form adenosine diphosphate, ADP, through the hydrolysis reaction ATP(aq) + H2O(I) → ADP(aq) + Pi(aq) + H+(aq) . The standard reaction Gibbs energy, ΔrGΘ, for the hydrolysis of ATP to ADP is+ 10 kJ mol-1 at 298 K.This assumes that the concentration of hydrogen ions is 1 mol dm-3 . (a) In biochemistry, it is common practice to assume an alternative , and more realistic, standard state for which pH = 7. What is the corresponding standard reaction Gibbs energy, denoted ΔrGΘ, for this biological standardstate? (b) What is the Gibbs energy of reaction in an environment at 37 °C and pH = 7 in which the ATP. ADP. and P; concentrations are all (i) 1.0 mmol dm-3, (ii) 1.0 μmol dm-3 ?arrow_forwardA constant current flows for 3.75 h through an electrolytic cell containing aqueous AgNO3(aq). During this time, 2.00 g of silver are deposited on the electrode. What is the current flowing through the cell?arrow_forward
