For each of the following cases, decide whether the pH is less than 7, equal to 7, or greater than 7. Equal volumes of 0.45 M acetic acid, , and 0.45 M are mixed. The pH is . 25 mL of 13 M is mixed with 13 mL of 0.026 M . The pH is . 100 mL of 0.10 M is mixed with 50 mL of 0.20 M . The pH is . 48 mL of 0.20 M is mixed with 48 mL of 0.40 M .

Draw any one of the skeletal structures of a 2° alkyl bromide having the molecular formula of c6h13br and two stereogenic centers. indicate chirality by using wedge and hashed wedge notation. lone pairs do not need to be shown.

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(ii) carbonate, in concentrated sulfuric acid. the sulfuric acid reacts with the copper(ii) carbonate to produce a blue solution of copper(ii) sulfate. scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: (s) (aq) (s) (aq) suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. he adds powdered iron to a copper(ii) sulfate sample from the plant until no more copper will precipitate. he then washes, dries, and weighs the precipitate, and finds that it has a mass of .

What are the coefficients to balance the following equation? ba+br=babr2
