When carbon dioxide dissolves in water, it undergoes a multistep equilibrium process, with Koverall = 4.5×10-7, which is simplified to the following: CO.(g) + H,O(1) H,CO;(aq) HCO, (aq) + H;O*(aq) H,CO3(aq) + H,O(1) (a) Classify each step as a Lewis or a Brønsted-Lowry reaction. (b) What is the pH of nonpolluted rainwater in equilibrium with clean air (Pco, in clean air = 4X10-4 atm; Henry's law constant for CO, at 25°C is 0.033 mol/L-atm)? (c) What is [CO,2-] in rainwater (K, of HCO,- = 4.7X10-11)? (d) If the partial pressure of CO, in clean air doubles in the next few decades, what will the pH of rainwater become?

com/alekscgi/x/Isl.exe/1o_u-IgNslkr/J8P3JH-IBEWe Maps O MEASUREMENT Lindsay Adding or subtracting and multiplying or dividing measurements chemistry student must write down in her lab notebook the concentration of a solution of sodium hydroxide. The concentration of a solution equals the mass what's dissolved divided by the total volume of the solution. re's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 6.050 g dlo - She put some solid sodium hydroxide into the graduated cylinder and weighed it. With the sodium hydroxide added, the cylinder weighed 96.4 g. - She added water to the graduated cylinder and dissolved the sodium hydroxide completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 151.66 mL. Ar at concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. -1 gmL
