Chlorine is more reactive than bromine. Bromine can be prepared by adding chlorine to an aqueous solution of sodium bromide. The reaction is represented by the equation
2 NaBr(aq) + Cl2(g) = Br2(l) + 2 NaCl(aq)
How many grams of bromine are formed if a solution containing 25.0 g of aqueous NaBr(s) and 25.0 g of Cl2(g) are reacted?
What is the limiting reagent? What is the theoretical yield of acetanilide? What is the percent yield if 3.3g of acetanilide is obtained?
Sodium nitrate decomposes upon heating to form sodium nitrite and oxygen gas. This reaction is sometimes used to produce small quantities of oxygen in the lab. How many grams of sodium nitrate must be heated to produce 128g of oxygen?
In the mammalian system, typical fatty acid synthesized for energy and storage are generally have 16 carbons. However, the typical fatty acid found in breast milk is C12 to C14. Explain how the synthesis of fatty acids in the mammary glands differ..
