A carbonated beverage is made by saturating water with carbon dioxide at 0°C and a pressure of 3.0 atm. The bottle is then opened at room temperature (25°C), and comes to equilibrium with air in the room containing CO 2 ( P CO 2 = 1.0 × 10 − 3 M / atm ) . The Henry's law constant for the solubility of CO 2 in water is 0.0769 M/atm at 0°C and 0.0313 M /atm at 25°C. (a) What is the concentration of carbon dioxide in the bottle before it is opened? (b) What is the concentration of carbon dioxide in the bottle after it has been opened and come to equilibrium with the air?

Q1: Curved Arrows, Bronsted Acids & Bases, Lewis Acids & Bases
Considering the following reactions:
a) Predict the products to complete the reactions.
b) Use curved electron-pushing arrows to show the mechanism for the reaction in
the forward direction. Redraw some of the compounds to explicitly illustrate all
bonds that are broken and all bonds that are formed.
c) Label Bronsted acids and bases in the left side of the reactions. Label conjugate
acids and bases in the right side of the reactions.
d) Label Lewis acids and bases, nucleophiles and electrophiles in the left side of the
reactions.
