Calculate the pH of a solution containing 0.15 M acetic acid and 0.25 M sodium acetate. For acetic acid, Ka= 1.8 X 10-5. Either as a buffer system or use ICE table. NaOAc is strong electrolyte
If 25 g of al and 100g of br2 are reacted and if 64.2 grams of aliminum bromide is formed. what is the theoretical yield
The Born-Haber cycle is a series of steps that represent the formation of an ionic compound from a metal and a nonmetal. For example, the steps in a Born-Haber cycle for the formation of NaCl(s) consist of sublimation of the metal Na atom
Calculate the theoretical yield of iron in the reaction of 254 g of iron (III) oxide with 25.0 g of carbon, according to the equation 2Fe2O3(s) + 3C(s)> 4Fe(s) +3CO2(g)
Consider the following reaction, where X represents and unknown element. 6X(s) + 2B2O3(s0 = B4X3(s) + 3XO2(g) If 165 grams of X reacts completely with diboron trioxide to rproduce 2.29 mol of B4X3.
