A solution is prepared such that the initial concentration of $Cd^{2+}$ is $3.80 \times 10^{-2}$ M and the initial concentration of $Br^-$ is $7.50 \times 10^{-2}$ M. $Cd^{2+}$ and $Br^-$ are allowed to react as shown below to establish equilibrium with the complex $CdBr_4^{2-}$. The equilibrium concentration of the complex $CdBr_4^{2-}$ is determined to be $2.9 \times 10^{-3}$ M. $Cd^{2+}(aq) + 4Br^-(aq) \rightleftharpoons CdBr_4^{2-}(aq)$ What is the formation constant, $K_f$, for this complex?

You discover an organism that has scaly skin and is aquatic but returns to the land to reproduce. What else would you expect to find in this organism? 1 You would anticipate amniotic eggs from an organism with scaly skin that returns to land for reproduction. One important adaptation that enables some species, including reptiles, to breed on land is the use of amniotic eggs. Specialized membranes found in amniotic eggs shield and nourish the developing embryo, allowing it to grow outside of an aquatic environment. Correct?

Why is VisionSpring, an organization devoted to the problem of poor eyesight in the developing world, classified as a hybrid model of social entrepreneurship? It is a for-profit business but it is classified, legally, as a nonprofit for tax purposes. Its primary concern is that of a nonprofit, but it is a for-profit company. It relies on both venture-funded philanthropy and earned-income activities to sustain itself. It is a nonprofit that functions as a for-profit enterprise.

The concentration of citric acid, a triprotic acid, in a carbonated soft drink was to be determined. Step 1: A solution of NaOH(aq) was standardised by titrating it against 25.00 mL aliquots of a solution of the monoprotic acid potassium hydrogen phthalate (KHP). The KHP solution was produced by dissolving 4.989 g in enough water to make 100.0 mL of solution. The molar mass of KHP is 204.22 g mol$^{-1}$. The results of the standardisation titration are given in the table. Titration Volume NaOH (mL) 1 28.60 2 27.40 3 27.20 4 27.60 Step 2: A 75.00 mL bottle of the drink was opened and the contents quantitatively transferred to a beaker. The soft drink was gently heated to remove $CO_2$. This was done as any dissolved $CO_2$ adds to the acidity of a solution. Step 3: The cooled drink was quantitatively transferred to a 250.0 mL volumetric flask and distilled water was added up to the mark. Step 4: 25.00 mL samples of the solution were titrated with the NaOH(aq) solution. The average volume of NaOH(aq) used was 13.10 mL.
