When chlorine gas is bubbled into a solution of a sodium bromide, the sodium bromide reacts to give bromine, a red- brown liquid, and sodium chloride (table salt). A solution was made by dissolving 20.6g of sodium bromide in100.0g water. After passing chlorine through the solution, investigators analyzed the mixture. It contained 16.0 g of bromine and 11.7 of sodium chloride. How many grams of chlorine reacted?
Any help on how to do or start this problem. Calculate the change in pH of rainwater resulting from an increase in the P of CO2 from 10^-3.5 atm to 10^-3.0 atm due to fossil fuel emissions.
